High 5's didn't exist until 1977-  Yep, its true!  It is said that High 5's began in baseball when Dusty Baker reached up to slap a teammate's hand.  The guy's hands just happened to be up in the air after a big play and Dusty decided to give it a slap.

Play-Doh was originally designed as a wallpaper cleaner.

Good Ol' Issac Newton invented the doggy door!  It actually started out as "cat flaps."  Newton had two cats and he wanted to make it more convenient for them to go in and out as they pleased.

Michael Jackson did not invent the moonwalk.  It was actually developed by a guy named Bill Bailey!
