Nastiest thing you've ever seen in a porn?

[humperbink]

There used to be an old picture floating around the web showing a naked old overweight man sitting in front of the computer with the message "You never know who you're talking to" that freaked me out, but that was when I was young and wasn't used to seeing gross things like I am now.

I don't know if this counts, but the nastiest thing was a woman shitting and that kind of stuff is just plain ass nasty.
