Imagine losing a hugely expensive spacecraft due to a simple mix-up between English and metric measurements . That is exactly what happened to NASA in 1999 when a Mars orbiter designed by Lockheed Martin was lost in space.

The confusion caused a malfunction on the $125 million craft, resulting in the probe’s loss. Although it was unusual for Lockheed to use English measurements for a NASA design (since NASA had stipulated using metric measurements for many years), there were still several instances where the error should have been caught but wasn’t.

Toys ‘R’ Us blunder

If you think an action figure of a drug dealer isn’t the best idea for a toy store , you’re not alone. Yet, for some reason, Toys "R" Us decided otherwise in October 2014, possibly hoping to cash in on the massive success of the Breaking Bad TV series.

Unsurprisingly, the giant toy retailer was forced to pull from its shelves four collectible dolls based on characters from the AMC hit show, each doll featuring a detachable sack of cash and a bag of meth.

Apple Maps' rocky beginnings

When Apple decided to launch its own map application on iOS devices after a conflict with Google in 2012, users quickly realized that the Apple app was not nearly as launch-ready as it should have been .

Locations were mislabeled, roads were missing, and it occasionally steered people in entirely the wrong direction. The problem was eventually, though largely, resolved, but it was an embarrassing misstep for a company known for never launching a product before it was as near-perfect as possible.

Bank of America debit card fee

Image: Ali Mkumbwa

Back in 2011, when the backlash against the banking industry had not yet reached its boiling point, Bank of America announced it would charge customers $5 per month to use their debit cards .

It was a bad business decision. More than 300,000 people signed an online petition, and Fox Business Network’s Gerri Willis cut up her debit card on air. The bank pointed to federal regulations as the reason for the charge but ultimately capitulated to consumer demand after a month before the fees went into effect.

$33 airline tickets from Toronto to Cyprus

If buying a business class ticket regularly priced at $2,558 for just $33 sounds too good to be true, it probably is. Except in 2006, when an Alitalia employee accidentally forgot to input two extra zeros when pricing business-class tickets from Toronto to Cyprus.

Due to the exchange rate on that day and the blunder, hundreds of buyers managed to snag fares for just $33. The airline honored those deals, accepting the heavily discounted price for the 509 people who purchased tickets before the error was detected.

As the folks at NASA and Alitalia have shown us, small errors can lead to costly mistakes. The following blunder comes courtesy of Lockheed Martin , which issued a contract to a customer with a missing comma in the sale price .

The astute customer held the aerospace company to the contract, costing Lockheed Martin $70 million for a C-130J Hercules aircraft in June 1999.

Sears misses the ship

A retail giant that faced a situation similar to the one Kodak faced—embrace the new and unknown or cling to the old, successful recipe—Sears sold everything from socks to tires via mail order, shipping across the U.S.

Choosing to stick with the old method, the company ended its catalog and delivery business in 1993 . In 1994, Amazon was founded , filling the business void that Sears had just created. The rest is history.

Passing on Microsoft

$60 million might seem like a lot of money to us regular folks, but for someone with very deep pockets like Texas businessman and two-time U.S. presidential candidate Ross Perot, it wasn’t all that much.

In 1979, he was offered the chance to buy Microsoft for that sum. However, his final offer to the tech company was just $15 million, and as a result, the Texan missed out on the opportunity to own what would become one of the biggest companies in the world .

Blackberry sticks with the old

Another case of a brand sticking with the old instead of embracing the new, BlackBerry was all the rage at the start of the 21st century— until Steve Jobs came along with the Apple iPhone .

While BlackBerry Messenger was extremely popular, with over 80 million users worldwide, the device lacked the new touchscreen functionality and sleek design of the Apple product. From being a market leader, BlackBerry’s market share plummeted to 0.2% by 2016.

RadioShack’s downfall

Image: Jelleke Vanooteghem

Not so long ago, RadioShack was a familiar presence on the streets and the go-to place for buying batteries and electronics. But it was that same brick-and-mortar presence, coupled with a reluctance to embrace e-commerce , that ultimately led to its demise .

Eventually, poor profit margins on what they could sell, combined with a loan they couldn’t repay, brought down what was once the go-to place for electronics.

"Here’s Johnny!" - The Tonight Show Starring Johnny Carson

The Tonight Show is one of the longest-running and most influential programs in television history. The late-night show premiered in 1954, but Johnny Carson took over in 1962 and became the face of the show for three decades. It was Ed McMahon, Carson’s longtime sidekick and announcer, who gave birth to the iconic introduction: "Heeeeeere’s Johnny!" The phrase took hold so firmly in American culture that it was referenced endlessly across other shows and media, most famously parodied to terrifying effect by Jack Nicholson in Stanley Kubrick’s The Shining (1980).

"What’chu talkin’ ’bout, Willis?" - Diff’rent Strokes

It’s impossible not to picture Gary Coleman’s face when you hear "What’chu talkin’ ’bout, Willis?" The line, uttered by Arnold (Coleman) to older brother Willis (Todd Bridges), became so famous that it’s still used today to express confusion, even by young people around the world who don’t know it comes from the NBC sitcom Diff’rent Strokes (1978–1985). The catchphrase helped catapult Coleman to international fame, but it was repeated so often that, by the later seasons, he admitted he sometimes refused to say it.

3

"Ayyyyyy!" - Happy Days

Yes, the power of a catchphrase can be so strong that some of the most memorable ones are just one consonant-free syllable. A perfect example is the signature line of Arthur Fonzarelli, A.K.A. Fonzie, or "The Fonz," from Happy Days (1974–1984). Played by Henry Winkler, Fonzie was the coolest guy on TV, so all it took was a leather jacket, a thumbs-up, and an "Ayyyyy!" to make him immortal.

4

"Dy-no-mite!" - Good Times

Actor Jimmie Walker rose to fame playing J.J. Evans on the American sitcom Good Times (1974–1979). His clever and energetic character had a trademark: "Dy-no-mite!", his exclamation of excitement, approval, or surprise. The line became so famous that it appeared everywhere, from T-shirts to posters, and for many viewers, it’s the thing they most remember about the show.

Although the line was undeniably a hit, the actor admitted in later interviews that he wasn’t entirely sure it would take off. Who could have predicted what was coming?

"I love it when a plan comes together!"- The A-Team

"I love it when a plan comes together!" was the iconic catchphrase delivered by George Peppard’s character in The A-Team (1983–1987). At the end of many episodes of the action series, Lieutenant Colonel John "Hannibal" Smith would light or just hold his cigar as he delivered the line, signaling that his plans (usually elaborate, risky, and a little over the top) had worked out perfectly. Over time, the phrase became part of popular culture and is still used today whenever everything falls into place.

6

"Book 'em, Danno" - Hawaii Five-O

"Book ’em, Danno" was the iconic line delivered by Jack Lord’s character, Detective Steve McGarrett, to his partner Danny "Danno" Williams (played by James MacArthur) on Hawaii Five-O (1968–1980). The utterance often came at the end of an episode when the bad guy had finally been caught. It became hugely popular and turned into a cultural shorthand for "case closed" in the 1970s.

7

"Lucy, you got some 'splaining to do!"- I Love Lucy

Desi Arnaz and Lucille Ball played the ultimate sitcom couple, Ricky and Lucy Ricardo, on I Love Lucy (1951–1957). Whenever Lucy got caught up in one of her classic schemes or hilarious misunderstandings, Ricky would step in to deliver some version of "Lucy, you got some ‘splaining’ to do!"

Even though the line was never delivered exactly the same way, Ricky would always demand an explanation in similar terms, with variations like "Lucy, something needs ‘splaining’" or "What needs ’splainin’?"

"Is that your final answer?" - Who Wants to Be a Millionaire?

Maybe it’s just nostalgia, but it’s hard not to feel the tension when you hear "Is that your final answer?" That classic line from Who Wants to Be a Millionaire? originated with Chris Tarrant, the original host of the British version, which debuted in 1998. But it was Regis Philbin, host of the American version (which premiered in 1999), who helped the phrase achieve worldwide fame.

The question added a moment of suspense, often making contestants second-guess themselves. Over time, its impact went far beyond the game, becoming an indisputable part of the cultural lexicon

"Live long and prosper" - Star Trek

You may remember Leonard Nimoy’s voice as Spock delivering his signature "Live long and prosper" in the original Star Trek (1966–1969). As a traditional Vulcan greeting, the line was often paired with the iconic hand gesture, where the fingers split to form a "V" shape. The phrase went on to transcend generations, which makes it even more surprising that it wasn’t part of the original script; it was Nimoy who came up with both the gesture and the phrase for the show.

10

"Norm!" - Cheers

Cheers (1982–1993) is one of those shows that’s hard to forget, and anyone who’s seen it will instantly remember the shout of "Norm!" This was the familiar greeting from the bar’s staff and regulars every time Norm Peterson, played by George Wendt, walked through the door. Norm is one of the few characters to appear in all 275 episodes of the series, so that moment became a beloved and frequent (very frequent) ritual.

If it’s not in use, turn it off

Image: Chris Haws

We start the list with this well-known advice: turn off the lights when nobody is in the room .

Additionally, switch off appliances completely rather than leaving them on standby, as standby mode continues to consume electricity. Most computers have energy-saving settings that automatically turn off the computer and screen after a period of inactivity.

2

Keep the temperature where you need it

Image: Natalia Y.

Whenever you are heating or cooling a room, remember to close the doors and windows that connect to other unoccupied parts of the building . This way, the heating or cooling equipment you are using will not require more energy than is necessary to maintain the desired temperature where you are.

During cooler months, ensure your curtains or blinds are properly sealed to keep the cold out. In warmer months, keep your curtains closed during the day to prevent heat from entering.

3

Wash and dry clothes once the basket is full

Image: engin akyurt

Avoid using your washing machine when your laundry basket is only half full; instead, use it when you have accumulated a full charge. Also, remember to select the appropriate washing cycle to optimize energy use.

On a related note, clothes dryers consume a significant amount of energy, so consider hanging clothes outside to dry or using a fan to help dry them indoors.

4

Save energy in the kitchen

Image: Jason Briscoe

Your kitchen offers many energy-saving opportunities. The fridge, one of the most energy-intensive appliances, runs 24/7 for obvious reasons but measures can be taken to make it a more efficient device. The ideal fridge temperature for the fridge is between 35° and 38°F. Make sure the door seal is tight, with no gaps or cracks that allow cold air to escape.

As for cooking, always put frozen food in your fridge in the morning to thaw out and reduce cooking time in the evening. Whenever possible, use a microwave, as it consumes significantly less energy than an electric oven. Plan to cook more and have leftover meals for the next day or the week ahead. Keep leftover meals in the freezer for convenience and minimal waste.

Smart heating and cooling

Image: Everett Pachmann

It may be tempting to adjust the thermostat a degree or two above or below the recommended settings depending on the season, but there is good reason to avoid doing that. Every degree above 20 can increase your heating bill by up to 10%. In winter, set your thermostat between 18 and 20 degrees. In summer, aim for 26 degrees or higher.

Additionally, some ducted systems allow you to disable heating or cooling in unoccupied rooms, which can help save energy.

6

Use energy-saving LED lights

Image: Anton Belashov

LED lighting has been around for a while and can save up to 80% on lighting costs. LED bulbs consume less power and last longer, which means that users spend less money and time replacing them.

Another perk, LEDs generate very little heat compared to incandescent and halogen bulbs, which convert much of their energy into heat. This can reduce cooling costs, especially in warm climates.

7

Solar energy

Image: Andreas Gücklhorn

The energy given to us by the sun can be harvested in solar panels that reduce the amount of energy we need to buy from the electricity company . Similarly, solar hot water systems can minimize gas usage, reducing reliance on gas-fired water heaters.

Solar panels and solar hot water systems used to be very expensive and had to be replaced much more often but, their costs have dropped significantly in recent years, making them more accessible.

8

TV settings

Image: Jonas Leupe

Today's high-definition televisions use around 60% less energy than earlier models. However, some Internet-ready models consume extra power even when turned off due to a "quick start" feature that enables faster boot-up . You can disable that option in your television's settings .

While perusing through the settings, you can also see if your model has an automatic brightness control, which will adjust the picture brightness to the level of light in the room. This can make a big difference in energy consumption.

Efficient appliances

Image: Vlad Zaytsev

Most of today's new appliances use half the energy of those from a couple of decades ago. If you're thinking of buying a new one, look for products with the Energy Star label, as they typically use 10 to 40 percent less energy than other models.

If you are going to buy a new computer, keep in mind that laptops use significantly less energy than desktop versions.

Insulate your roof

Image: Erik Mclean

Temperature affects air in different ways: heat rises, while cool air sinks. This means that if a house's roof is not properly insulated, heat will escape in the winter, and the cold from outside will seep in through the roof.

An insulated ceiling can make a big difference to your energy bills . Effective ceiling insulation can save up to 20% on cooling and heating costs.
