When she arrives home, lights some candles, slips into something comfortable, and puts the tape into the VCR. To her disappointment, there's nothing but static on the screen, so she calls the video store to complain. 

"I just rented an adult movie from you and there's nothing on the tape but static." 

"Sorry about, that,"replied the store clerk. "We've had problems with some of those tapes. Which title did you rent?" 

The blonde replied, "It's called 'Head Cleaner.'"
