Pro wrestlers are in the business of kicking ass.  It doesn't matter if it's a celebrity, a midget, or some guy wearing nothing but blue briefs, pro wrestlers know they are going to have to kick something's ass when they get in the ring.  Check out this video of wrestlers kicking the ass of things that don't even have asses.

I love how Rick Flair is featured in this video so often.  Nobody did crazy like the Nature Boy even though, the dude wrestling the sex doll gives him a run for his money. Also, lol at The Rock beating up Al Snow's head.  I totally remember watching that episode.
