Main Character: Silvia Low-Knobs, Professional Prostitute
Supporting Characters: Tiny Tim (Tiny Guy), Alexis Spits (Silvia's roomate) and whoever you make up.

Instructions: I'll start with four words, and everyone else chimes in with four more words, eventually constructing sentences, paragraphs and a story that will, undoubtably, make no sense. See thread Two Word Story for an example.
Point: None.
