A blonde named Mary decides to do something really wild.

A blonde named Mary decides to do something really wild. Something she hasn't done before, so she goes out to rent her first X-rated adult video. She goes to the video store, and after looking around for a while, selects a title 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, 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, she says. Sorry about that. We've had problems with some of those tapes. Which title did you rent? the clerk replies. Head Cleaner, Mary replies.
