I watched something a few years ago that is very like "Casting Couch" in that some guys kindof setup a fake movie and cast loads of women to interview for it and have sex with etc. one classic line/scene I remember is.
Women are discussing how to tell how big a mans penis is and one woman says "its all todo with the power of the pee" after hearing this one of the guys goes past a line of girls and uses a fire extinguisher in the urinal to make it sound like he has strong pee and the girls are impressed when he leaves the toilet.

Any ideas what its called??
Sorry if a little vague.
