The problem with US wrestling is that it's just too straight-edge. Greased up men trying to pin each other might pass for entertainment in dubious 'saunas', but it's a little old hat and predictable by 2009 standards. If you want bat-shit crazy wrestling you really need to go south of the border and check out Mexico's Wrestling Federation (Lucha Libre). It's as over the top and ridiculous as you could hope for.
Mexican wrestling distinguishes itself from its US counterpart in two main areas; the face masks and the style of wrestling. The whole face mask thing started in 1942 with a guy called El Santo (The Saint), he made his debut wearing a mask and ended up defeating a billion other wrestlers in a caged death match. His rise coincided with televised wrestling matches in the 1950s and he was totes famous. Soon everyone had a mask.
Mexican wrestling is also known for it's aerial moves. Basically, the dudes tend to be smaller and faster than their US counterparts. Rather than grappling with each other, they prefer insane fly kicks and aerial takedowns that can rip a man's spleen out. Ghetto.
