"Showboating Fighters Get KTFO" — that's knocked the F out — is a popular YouTube genre. But before the internet, Anthony "Hollywood" Hembrick practically invented the form. An undefeated light-heavyweight, Hembrick danced up a choreographed storm with his cornermen before getting KO'd in the first round of a fight on national TV. The former U.S. Olympic captain eventually challenged for the world title, but he'll always be best remembered for that one humbling night. Originally published Dec. 9, 2017.
