Hmm.... lets see if we can get this off of tubgirl, seeing as most people have no desire whatsoever to even think about it.
My favorite wierd porn:
www.ampulove.com
Only reason I find it so amusing is because their old frontpage had a girl with stumps for arms and legs in a "seductive" pose on it, and when my friend saw it, she immediately tried to imitate it. It was one of the funniest things I've seen in a while.
midgit porn is bizarre, too. Actually, you want wierd porn, go to yahoo, search for "porn" and you'll get a ton of different categories.
