« No one never knew that Tom Cruise and Chuck Norris were bitter enemies until one evening on the set of Cruise's movie "Cocktail". That evening, Tom Cruise was practicing his role as a bartender by serving Chuck Norris Budweiser in a glass. Tom repeatedly asked Chuck throughout the night if he looked cool flippin the rum and vodka bottles while serving up some shots to a few ladies down from the bar. Chuck responded with an occasional grunt. Half way through the evening, Tom noticed Chuck's glass was half full. Tom asks "Ok man...is your glass half full, or half empty?" Chuck with anger in his voice replied; "How dare you ask me those kinds of questions!" then snaps and says, "Neither... I'm half drunk, give me more" while he grabbed one of the girls at the bar by the neck and ate her head. »
