Who would win in a fight?

I know a person who was once asked this question and he replied "Are you a moron?" then he asked "Who would win in a football game, a team 5A all-stars, or a team of amateur boxing champions?" Then he asked "who would win in a football game between a team of Muhammad Alis and a team of Lawrence Taylors?" Then rightfully, the asker felt like a complete idiot and never asked a stupid question again.
