Tallahassee Water-Slide
First, you will need to find two lesbians that are willing to be filmed while in the act. Next, tell the girls that it is ok for them to get started without you while you "get your camera set up." Leave the room, get naked and come back with the camera. While one girl is eating the other out, shit on the girl's chest who is receiving. Quickly turn around and piss on the same girl's chest. Your river of urine will carry your shit directly into the mouth of the unsuspecting rug muncher.
I'm goin to the gay bar, gotta get some dikes to set up a Tallahassee Water-Slide.
