"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.

"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.

"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.

"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.

"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.

It was invented in Switzerland

While the name suggests a US origin, the technology that created American cheese actually began in the heart of the Alps. It was developed in 1911 by Swiss researchers Walter Gerber and Fritz Stettler, who were looking for a way to extend the shelf life of their country’s famous Emmental cheese.

The problem with traditional cheese is that it eventually dries out, molds, or separates into a greasy mess when heated. By shredding the cheese, adding sodium citrate, and heating it, the Swiss duo discovered they could create a stable, smooth product that didn't separate. While they weren't trying to create "American" cheese as we know it today, their emulsification process laid the foundational science for every single-wrapped slice produced today.

2

It was popularized by a Canadian

The man responsible for the global dominance of American cheese was James L. Kraft. Ring any bells? Kraft was a Canadian immigrant who moved to Chicago in 1903. While he didn't invent the concept of processed cheese, he perfected the industrial scale of its production and marketing.

Kraft noticed that retailers struggled with cheese spoilage; if a wheel of cheddar didn't sell quickly, it was a total loss. He experimented with various methods of heating and blending cheese until he found a formula that could be canned and shipped long distances without spoiling. In 1916, he received a patent for his "processed cheese," and during World War I, the U.S. government purchased millions of pounds of it for soldiers, cementing its privileged place in the American diet.

3

It was almost called "Embalmed Cheese"

When processed cheese first hit the market, it had its detractors. Traditional cheesemakers were horrified, and so were pure food advocates. These critics argued that the product shouldn't even be called cheese. They’ve even gone so far as to call it "embalmed cheese" because of its unnaturally long shelf life and the chemical emulsifiers used to keep it stable. Yet, Kraft’s marketing prowess and the sheer convenience of the product ultimately won the naming battle. At least in the court of public opinion.

4

Technically, it isn’t cheese

Kraft may have won the battle among the people, but legally, American cheese is not considered cheese. If you look closely at the packaging, you will rarely see the word "cheese" on its own. Because of strict FDA regulations, most varieties are legally classified as "Pasteurized Process Cheese Product" or "Pasteurized Process American Cheese Food."

To be labeled "cheese," a product must be made primarily of milk, salt, and enzymes. Processed American cheese, however, is made by blending real cheese—usually cheddar or Colby—with emulsifying salts, whey, and sometimes extra milk or fats.

5

Any cheese can be made into American cheese

The term "American cheese" refers more to a process than a specific flavor. In theory, you could make "American-style" brie, blue cheese, or parmesan. The defining characteristic is the addition of an emulsifier, which breaks down the proteins and allows the fats and water to stay together.

In fact, some high-end chefs now make their own artisanal American cheese with aged cheddars processed with sodium citrate to create a slice that has the complex flavor of an expensive block but the melting point of a Kraft Single.

6

It isn’t naturally yellow

The vibrant orange-yellow hue of American cheese is entirely a cosmetic choice. Traditionally, cheese color varied by the season; when cows ate fresh grass in the summer, their milk contained more beta-carotene, leading to a naturally yellowish cheese. To make their cheese look high-quality all year round, cheesemakers began adding dyes.

American cheese takes this tradition to the extreme. It is typically colored with annatto, a seed from the achiote tree. Without this dye, American cheese would be a pale, creamy white, which is how it is sold in many delis as "White American". Yes, that’s right, there is no flavor difference between the white and yellow versions.

7

It has an extremely low melting point

The scientific superpower of American cheese is its meltability. Traditional cheeses have a protein structure that tightens when heated, which is why a slice of aged cheddar on a burger often results in an oily puddle and a rubbery clump.

Because of the emulsifying salts, the proteins in American cheese can withstand heat without clumping together. This gives it an incredibly low and stable melting point, transforming the slice into a silky sauce. This is why it remains the undisputed king of grilled cheese sandwiches.

It’s been in space

When you're hurtling through orbit in a cramped capsule, you need food that is stable, easy to eat, and won't crumble into thousands of tiny, electronics-clogging pieces. American cheese fit the bill perfectly for early NASA missions.

Processed cheese in tubes or cubes was a staple of the Apollo missions. Because it doesn't separate or sweat oil in varying temperatures and pressures, it was one of the few dairy products that could reliably provide flavor and calcium to astronauts.

9

It helped bring cheese to the masses

Before the advent of processed cheese, cheese was often a seasonal luxury. It was difficult to transport, expensive to store, and highly variable in quality. James L. Kraft’s invention changed that. By creating a product that was uniform in flavor and shelf-stable, he made cheese affordable and accessible to every corner of the United States.

10

The U.S. Government once gave it out

The U.S. government not only bought tons of American cheese during World War I. In the 1980s, the term "government cheese" became a thing. During a period of dairy surpluses, the government bought millions of pounds of cheese to prop up prices for struggling farmers.

To avoid letting it rot, the Reagan administration began distributing five-pound blocks of cheese to low-income families, seniors, and schools. For many who grew up in that era, that pale orange processed cheese was a lifesaver.

Open the windows

Yes, you read that right. A sitting US president can’t just get up and open the windows of the White House to enjoy a beautiful day. While there’s no law against it, the protocols state that any action that could pose a security risk to the commander-in-chief must be carefully reviewed and approved by the staff.

2

Go to the cinema

Going to the movies is one of life’s simple pleasures. Unfortunately, if you’re the president, it’s not one of your options. While it’s not officially forbidden, crowded and dark spaces like movie theaters represent serious security risks. Luckily, the White House has its own private screening room, so the president and his family can still enjoy movie night at home.

3

Attend their children’s events

You’ll rarely see a president at their kids’ school plays or sporting events. And it’s not because they’re bad parents; it’s because regulations discourage them from attending. With so many people, children, and things happening at the same time, keeping the commander-in-chief safe in those settings is nearly impossible.

4

Buy their own tech devices

When a new iPhone hits the market, many rush to buy it, but presidents can’t make this decision on their own. Any electronic device, like a smartphone or tablet, could be vulnerable to hacking or espionage. So while presidents can use cell phones, theirs must be secure, vetted, and government-approved.

5

Block people on social media

And that isn’t the only restriction on cell phones. Presidents who use their social media accounts for official communications are advised not to block people in their official POTUS account, since doing so could be seen as suppressing free speech. On the other hand, they can block users on personal accounts.

6

Go out alone

The US president can’t just grab the keys and head out for a walk. Sure, strolls around the White House gardens are fine, but stepping beyond the gates is a different story. Anytime the president leaves the White House, even for a quick walk around the block, the Secret Service must secure the area, plan the route, and provide constant protection. Sounds a little overwhelming, right? But when you’re the commander in chief, safety always comes first!

7

Drive

Ever felt the urge to hop in your car and drive somewhere spontaneously? Well, if you’re the President of the United States, that’s off-limits. Security measures strongly recommend that presidents must always travel in a secure vehicle with a driver and a full security detail. In fact, the last president known to drive alone on the open road was Lyndon B. Johnson (1963-1969).

8

Fly on commercial airlines

Just as security protocols strongly discourage the president from driving alone on open roads, flying on commercial airlines is also off-limits. Imagine being hundreds of feet in the air, locked in with strangers; it could be extremely unsafe when you’re the president of the United States. Implementing proper security measures would be too complicated, and with a large presidential staff, there might not even be enough seats for everyone.

9

Accept expensive gifts

Presidents receive many, many letters and gifts from the public, but not all of them can be accepted. The US Constitution and federal law require presidents to decline overly expensive gifts, whether they come from foreign leaders or everyday citizens, to prevent any appearance of conflict of interest or corruption.

10

Discard official mail

Image: Wolfgang Vrede

Although it may seem like a harmless, ordinary task, the president can’t just start cleaning out their office or email inbox. All presidential correspondence, physical or digital (even spam!), is considered official government property. It must be processed or archived according to federal records regulations, and discarding anything requires a strict review process.
