Did you Know? Superman fought Muhammad Ali
"Float like a butterfly and sting like a bee." "Man of Steel, beware, I'm Muhammed Ali!" At least, that's what he could have said after knocking out Superman in a boxing match. Yes, indeed! DC Comics published Superman vs. Muhammad Ali in 1978. The match, which took place in an outer space boxing ring, saw Superman defeated, but he was unconcerned because it was all part of a plan to protect Earth from aliens.
