Though my comic reading days are long gone and over, I recently came across this bizarre concoction:
Superman Vs. Muhammad Ali 
Published in 1978 it tells the story of aliens trying to destroy earth unless they can find a person willing to fight one of their aliens in a boxing match. Ali volunteers, but so does Superman. In order to pick one challenger they must first fight each other on another planet. Superman is stripped of all his super-powers thanks to a red sun, and Ali teaches the man of steel the sweet science of boxing for their big event.
Kind of corny and certainly a product of its time when Ali was a big deal. Still, I thought it was entertaining and gave me a nice flashback from when I was reading comics as a kid.
Do you know of any other weird "Vs." comics?
