When it is around Christmas time and the radio stations are playing Christmas music 24/7, get into your buddy's car when he is not paying attention. Tune the radio into a Christmas station and crank the music up and shut the radio off. Next time he goes to start his car, Christmas music will be screaming out his speakers. Also can be called "The Christmas Jingle", "The Holiday Spirit", or "Leaving Somebody Jumping for Joy"
The Christmas special should be used mainly on people who are sensitive to loud noises, or people who hate Christmas music. However, it can be used on anybody as a good practical joke.
