bjphill asks if worms have legs. Indeed they do, at least the polycheates. Not really true legs, mind you, but rather parapodia, which are quite good enough for the worm's purposes. And while polycheates aren't ordinarily "brain worms," (see Baylisascaris procyonis for a real brain worm) they can be plenty scary in their own right. See Barry the Bobbit Worm: http://tinyurl.com/cnlkc6 (I'll leave it as an exercise for the reader to find out why they're called "Bobbit worms.")
This is good-natured poking, and it's nice to see Indians here speaking up against rampant political correctness. People always poke fun at nations, religions and what have you- it's a natural part of humor in general the world over.
