Ever wonder why no one sings the real "Happy Birthday" song on television?

The real song is actually protected by copyright. That means that it cannot be used without permission for commercial uses. This includes in movies, tv shows, and commercials. Don't worry though. You won't get sued for singing it at home for your own birthday party.

The original tune for the song was originally for a song called "Good Morning to All". Since then, it has been recorded with the words we now know, and as of 1934 it has been copyright protected. The copyright isn't set to expire until at least 2030. That's nearly 100 years after the original copyright was secured!

"Happy Birthday to You" brings in roughly $2 million in royalties every year. Much of that has gone to charities.

Mario's name used to be "Jumpman"

Mario's first appearance in a video game was in 1981's Donkey Kong. We now know of Donkey Kong as a star of his own games, but in the original Donkey Kong game, Donkey Kong was the villain who kidnapped a damsel in distress. Mario, whose name was "Jumpman" back then, had to rescue the damsel by jumping over barrels that Donkey Kong would throw at him. Back then, not only did Mario have a different name, but a different job as well. "Jumpman" was originally supposed to be a carpenter. Also, Mario's signature cap and mustache were added in because it made him easier to draw. The original Donkey Kong didn't have very good graphics, and it was easier for Mario (Jumpman) to have a hat and a mustache than have hair and a mouth.
