"Showboating Fighters Get KTFO" — that's knocked the F out — is a popular, and delicious, YouTube genre. But even before the internet, Anthony "Hollywood" Hembrick practically invented the form. An undefeated light-heavyweight contender, Hembrick danced up a choreographed storm with his cornermen before getting KO'd in the first round of a fight on national TV.
