I just heard about this one today. Its a movie with Wesley Snipes and Luis Guzman. There is a scene where a pretty girl, named Angela, farts in a car. The scene is on YouTube, just search for "Hard Luck deleted scene" or something to that affect. The actresses name is Jacquelyn Quinones too. It's really good for a fake one, I think.

I would post it, but YouTube is giving me a hard time. Not hard to find though.
