I could post a picture from a website of "butt worms" coming out of a guys asshole, but I won't. That picture even frightens me. Nasty, even thinking about it.

And yes, I have heard of butt worms from eating undercooked, or not cooked at all, hamburger and such. Lukcily, and I hope I never, EVER, get a butt worm. I would vomit uncontrollably. It just grosses me out.
