What's Bizarro?

Congratulations to everyone who understood Bizarro, but surely one doesn't need to be in another country (like me) to fail to understand the reference? What is it exactly, some kind of alternative universe that Superman encounters?

I remember very well the SUPERMAN comics from the 50s and there was something called a "bizarro" world. Superman had this wrinkled kind of face and looked mean-he was the opposite of Superman and everyone in that world were opposites of their real life counterparts. I believe this episode-which was one of the funniest I've ever seen-I mean, how many shows do you acutally laugh out loud at?, was the first time I've heard bizarro used since the 50s.

There were also quite a few episodes of the "Superfriends" cartoon in the 70's which featured Bizzaro Superman. I believe there was one episode in which Superman was somehow trapped in the Bizzaro world. Everything in it looked like a cubist's ultimate dream.

In article ,

	The Bizzarro World was a different "dimension" or
	"parallel universe", where everyone had a direct
	opposite counterpart. Superman's counterpart would
	try to do what he thought were good deeds, but were
	either practical jokes or were just destructive in
	nature.

	Essentially, all this Bizzarro episode was, was a
	look at the "parrallel universe" of these Seinfeld
	characters, where each is the opposite of those
	characters they represent.
