I gotta drop a fiver down for the holder of the all-time knock-out record. Barring the emergence of a supernatural freak-of-nature, no one will ever approach ol' Mongoose's record of 145 ko's... and he didn't make a career out of fighting chumps, either. All totaled, Moore fought nine world champions and seven Hall-of-Famer's. He had multi-fight series with some of the game's top fighters: he won four of five fights from Jimmy Bivins and Harold Johnson, and won all three of his fights against Joey Maxim. Moore was also the only man to have fought both Ali and Marciano. Retired in 1963 after TKO'ing Mike DiBiase...at the ripe age of 50!

He has one record that will never be broken-the world kayo record;nuff said.
