LMAO! Some of these pics...damn.
This thread made me think of the old Mr Hands video from a few years ago, a co-worker at my old job showed it to us one day and I'm still haunted by the images - they actually made a film about it, Zoo:
Zoo is a 2007 American documentary film based on the life and death of Kenneth Pinyan, an American man who died of peritonitis due to perforation of the colon after engaging in receptive anal sex with a horse. The film's public debut was at the Sundance Film Festival in January 2007, where it was one of 16 winners out of 856 candidates. Following Sundance, it was selected as one of the top five American films to be presented at the Directors Fortnight sidebar at the 2007 Cannes Film Festival.

Lol! I remember Mr. Hands, with the second guy helping the horse get into the guy. He died of colon damage, right?
