Did Ali set out to humiliate Foreman because Foreman ripped his new elegant coat at a boxers banquet? I read this in George's autobiobraphy By George when Foreman said he went up behind Ali and ripped either side of Ali's coat and then Ali called him a f*****g Christian while threatening to throw some bottles off the dais. Eventually 3 or 4 guys managed to drag Ali away with Ali still spewing expletives while contorting his face into an angry mask which Foreman found strange as Ali was such a religious man.
