A blond decides to do something she's never done before - rent a dirty movie. She drives to the local Video Warehouse and makes here way to the adult section in the back. After looking around at titles, she selects a something that sounds very stimulating.
She drives home, lights some candles, slips into something comfortable, and puts the tape in the VCR. To her disappointment there's nothing but static on the screen. She calls the store to complain and says, "I just rented an adult movie from you and there's nothing on the tape, but static."
The clerk apologized about the defective video and asked, "Which title did you rent?" The blond replied, "It's called 'Head Cleaner.'"
