Okay, I know that I'm a big dork, but I love this song:
The game goes that when you hear it in a movie you shout "Wilhelm!", which, when you do it a movie theater might make other patrons throw you out, causing you to do your own Wilhelm.
Anyway, we play this one in the car (the song, not the YouTube video or the game, although that would be impressive) and the kids scream at the appropriate parts. The funniest thing though, is that Blaise, in a very Pavlovian dog way, now screams whenever he hears the words "Wilhelm scream".
