Well I have to say the msot famous one have to be Tito vs. WW ..he had that messed up hairdo and the tight shorts that ...that I knew something bad was going to happend... Duran v. Hearns, Duran comes into the ring with this messed of a hair do...and we all know what happed there also....
Frazier shaved his head before Foreman. I heard a story that this was primarily because he was going for some sort of surgery on his eye and didn't want to be recognised. He sure as **** lost though.
Klitschko for the sanders fight. Had this shaggy do and unshaven look going on. He actually looked like a badass Ukranian gangster but of course...didnt really fight like one :dead
