Did you know that this pop music classic was actually composed for a movie? Diana Ross and Lionel Richie recorded "Endless Love" for the Motown label, and it was used as the theme song for the 1981 film of the same name, starring Brooke Shields and Martin Hewitt.

Produced by Richie, the song was released as a single from the film’s soundtrack. Although the film was a flop, the song became the top hit single in the United States that year. It reached number one on the Billboard Hot 100 chart and remained there for nine consecutive weeks.

"I Got You Babe" is arguably the biggest hit by Sonny & Cher, one of the most iconic musical duos in history . Sonny Bono wrote it late one night in their basement for his wife, Cher.

Recorded in 1965, the song became a smash hit, reaching number one on the Billboard Hot 100 chart. "I Got You Babe" is a beautiful hymn to love and loyalty , and it has been covered by various artists over the years.

Considered one of Donna Summer’s standout songs , "No More Tears (Enough Is Enough)" was recorded with Barbra Streisand in 1979. The song became so popular that several vocalists have recorded their own versions over the years.

Neither Donna nor Barbra ever performed the duet live together, but Streisand sang an excerpt during her Back to Brooklyn concert tour in 2012. At the time, she remarked that if Donna were still alive, she would have loved to perform it with her.

The former Beatle had already collaborated with the King of Pop on "The Girl Is Mine," featured on Jackson’s Thriller album. The song was so successful that they teamed up again to record "Say Say Say," the lead single from McCartney’s fourth solo album , Pipes of Peace .

Jackson wrote most of the lyrics, and the legendary George Martin produced the track. It was released in 1983 , along with a music video in which the duo plays a pair of con men selling a miracle potion. The video also featured cameos by Linda McCartney and La Toya Jackson.

Did you know this song wasn’t originally written as a duet? It was composed by Dennis Morgan and Simon Climie with Tina Turner in mind . Eventually, Aretha Franklin got the job, and the label later suggested a collaboration with George Michael.

Aretha and George released "I Knew You Were Waiting (For Me)" in 1987. Both artists later stated that they had a great time recording the song and the music video that followed. And it shows, because the tune reached number one on the Billboard Hot 100 and topped charts around the world.

Performed by Bill Medley and Jennifer Warnes, "(I’ve Had) The Time of My Life" was released in 1987 as part of the soundtrack for the movie Dirty Dancing . This pop ballad, with rock and soul influences, conveys a sense of celebration and joy, highlighting the importance of special moments that leave lasting memories.

The original version of this song was recorded in 1966 by C. Carson Parks and his wife, Gaile Foote, but it only became widely known in 1967 when Nancy Sinatra performed it with her father, Frank.

It may seem a little unusual for a father and daughter to sing a romantic duet, but their version of "Somethin’ Stupid" became a massive international hit . Although the song was revived in 2001 by another duo—British singer Robbie Williams and Australian actress Nicole Kidman—Nancy and Frank’s rendition remains the most iconic.

Kenny Rogers & Dolly Parton: "Islands In The Stream"

When the anti-disco backlash nearly ended their reign, the Bee Gees shifted their focus to writing hits for other artists. Originally, "Islands in the Stream" was intended as a soul song for Diana Ross or Marvin Gaye. However, it ended up becoming the quintessential country-pop duet—and one of the biggest hits of Kenny Rogers and Dolly Parton’s careers.

The song is named after Ernest Hemingway’s posthumous novel, but its lyrics speak to the joy of finding that one person you’ve been searching for your whole life. Pretty romantic, don’t you think?

Paul McCartney & Stevie Wonder: "Ebony And Ivory"

Paul McCartney and Stevie Wonder released "Ebony and Ivory" in 1982, and it was an instant hit. Written by McCartney, the song addresses racial integration , using the black and white keys of a piano—working together to create harmony—as a metaphor.

Fun fact: McCartney and Wonder filmed their parts of the music video separately due to scheduling conflicts, but the final result was seamless nonetheless.

This powerful and emotional ballad, performed by Joe Cocker and Jennifer Warnes, was released in 1982. The song was created for the soundtrack of the movie An Officer and a Gentleman and captures the essence of overcoming challenges and transcending through love.

There’s nothing like the charismatic and luscious voices of Marvin Gaye and Tammi Terrell to convince us of love’s healing power. "Ain’t No Mountain High Enough" was released as a single in 1967 and became a huge hit.

This romantic anthem is just one of the iconic collaborations by the duo that helped define the Motown era, thanks to their vocal harmonies and onstage chemistry . Their list of great soul duets also includes "Your Precious Love," "Ain’t Nothing Like the Real Thing," and "You’re All I Need to Get By," among others.

Anyone who has seen the movie Grease is probably a fan of this iconic tune.

Florida – Meter feeding for elephants

Image: AJ Robbie

Florida’s traffic code once required that if you tied your elephant, goat, or alligator to a parking meter, you had to pay the fee, just as you would for a car. It sounds wild today, but it’s rooted in a time when people actually rode animals into town.

Though it’s not actively enforced (we checked), the law technically still lingers on the books. So, you'd better leave your pet elephant behind from now on!

Idaho – Seniors and motorcycles don’t mix

Image: Harley-Davidson

In Idaho Falls, it’s long been rumored that a local ordinance makes it illegal for anyone over 88 to ride a motorcycle. That sounds oddly specific—and a bit ageist. Whether it was meant to encourage safety, misinterpreted, or inspired by one daredevil granny, no one’s quite sure.

While there's no sign of active enforcement (or even proof it still exists), the message seems clear: once you’re nearing 90, it might be time to stick to the golf cart.

Arizona – Don’t even think about driving in reverse

Image: Jerry Kavan

Arizona doesn't mess around when it comes to driving in reverse. On public roads, moving backward is a big no-no. While it’s unlikely you’ll get arrested for backing out of a driveway, pulling a full-speed reverse cruise down Main Street might land you in hot water. Arizona wants you to move forward in life—literally.

Illinois – You need a steering wheel to drive

Image: Zach Wiley

Well, isn’t that obvious? Apparently not—because Illinois actually has a law stating that you can’t drive a car without a steering wheel.

Even if it seems like common sense, laws like this were created during the early days of car modifications, when people got creative (and sometimes reckless). So, if you were planning to steer your car using a rope-and-pulley system… maybe don’t.

Maine – No Sunday car shopping

Image: Hilbert Hill

In Maine, it’s illegal to buy a car on Sunday. Dealerships are closed by law, making it impossible to seal the deal on the most relaxing day of the weekend. Why? The rule has roots in so-called "blue laws," which were designed to preserve Sunday as a day of rest. So in Maine, if you get a wild urge to car shop after church, you’ll have to wait until Monday.

Michigan – Streets are not for reading

Image: bruce mars

Michigan has a law that says you can’t sit in the middle of the road and read a newspaper. Yeah, no joke!

We know—it’s hard to imagine someone actually doing this (unless it was a very juicy headline), but the law’s goal is clearly about safety. Still, you have to admit the mental image is pretty great—just don’t try it unless you want to make the evening news.

New Hampshire – Bus fumes are not a high

Image: Lizgrin F

New Hampshire takes a hard stance on inhaling bus fumes "with intent to cause euphoria." That’s a legal phrase, not a band name. It’s part of the state’s broader anti-huffing laws, aimed at curbing substance abuse.

Well, that’s odd!

8

Vermont – Backfiring is a no-go in Rutland

Image: RoonZ nl

In Rutland, Vermont, letting your car backfire could technically get you in trouble. This law was probably put in place to cut down on noise or prevent panic during quieter times in history.

Today, it’s unlikely to get you arrested, but a surprise backfire might still earn you some serious side-eye from the locals. If you ask us, this should be a law everywhere!

Wisconsin – Hands off the handlebars? Not allowed

Image: Darko Pribeg

In Wisconsin, you’re not allowed to ride a bicycle with no hands. Even if you’re showing off your balance skills from the 1970s, the law says at least one hand must stay on the handlebars.

It’s all about safety—but if you’re feeling rebellious, maybe show off at the park. Just don’t do it on public roads. Keep it hands-on!

South Carolina – No trash hoarding in Hilton Head

Image: Alireza Mirzabegi

In Hilton Head, it’s illegal to store trash in your car. That’s right—your vehicle can’t double as a mobile garbage can. The law aims to keep the area clean and tourist-friendly, but it also sounds like a not-so-subtle jab at anyone using their backseat as a trash bin. Hilton Head wants pristine beaches and clean cars!

Clock change

Image: Jonathan Borba

US currency is full of symbolism, and the $100 bill is no exception. Since 1928, we have seen Independence Hall depicted on the back of this bill. But in 2013, it was redesigned, and one change stands out: the clock tower, which previously showed 4:10, now reads 10:30. Did you notice?

Jackie Kennedy’s choice

Image: Florida Memory

Jackie Kennedy played a key role in designing the coin that would feature the portrait of her ex-husband. When the U.S. Mint planned the Kennedy half dollar in 1964, she was consulted and provided input on various aspects of the coin, including its imagery and symbolism.

Not paper

Image: Giorgio Trovato

Although it is called paper money, our bills do not contain any paper at all. In fact, they are made of a blend of 75% cotton, 25% linen, and fine silk fibers embedded. This mixture is not random; it was specially chosen so that your bills can withstand everything: folds, wrinkles, stains, and even an accidental shower in the washing machine.

The unfinished pyramid

Image: Marek Studzinski

The one-dollar bill also has its secrets and details. On its back, you’ll find an unfinished pyramid, part of the Great Seal of the United States designed in the 1780s. Why unfinished? The pyramid has 13 steps, representing the original 13 colonies, and its incomplete form symbolizes the nation’s ongoing growth and expansion.

50% larger

Image: Bozhin Karaivanov

Before 1929, US banknotes were significantly larger, measuring approximately 7.375 x 3.125 inches. Today, collectors refer to these as "large-size" notes, sometimes even nicknamed "Horseblankets." In contrast, modern bills measure just 6.14 x 2.61 inches. The government decided to reduce the bill's size to cut production and design costs.

Andrew Jackson’s preference

Image: Giorgio Trovato

Andrew Jackson has been the face of the $20 bill since 1928, when he replaced Grover Cleveland. Ironically, Jackson was opposed to paper money. He didn't trust that form of payment, believing it could be easily manipulated. According to historians, the 7th U.S. President favored "hard money": gold and silver coins.

Alexander Hamilton’s portrait

Image: engin akyurt

Most portraits on US bills face left, with one exception: Alexander Hamilton on the $10 bill, the only one facing right (toward the viewer’s left). You might wonder why, but there’s no official explanation; it seems to have been simply a design choice.

"In God We Trust"

Image: rc.xyz NFT gallery

In 1956, Congress passed a law declaring "In God We Trust" the national motto, making it mandatory on all U.S. coins and banknotes. But this wasn’t its first appearance: the phrase first appeared in 1864 on the two-cent coin. Beyond faith, it also carried political weight, suggesting that God favored the Union during the Civil War.

The change that never happened

Image: Ryan Quintal

In 2015, the Treasury announced plans to redesign the $10 bill, stating that Hamilton's portrait would be replaced by that of an influential woman from US history. However, the change never happened. Why? Those years saw a surge in Hamilton's popularity thanks to the hit musical of the same name, leading the Treasury to backtrack on the replacement plan.

Criteria

Image: Live Richer

As is well known, not just any portrait can appear on US currency. But beyond historical significance, the figures on our bills and coins must meet other criteria you might not know: They must also be deceased and well recognized by citizens, ensuring that the people represented are familiar and meaningful to the public.
