Wilhelm Scream

This is something my son pointed me to a while back. Many, many movies use the same scream.  It sort of has become an in joke by movie makers.  Watch the video, you have heard it a zillion times but may not know it.
IMDB has a list of 225 movies and games with the scream. As you can tell from the video above, Lucas puts it in nearly every one of his movies. And it is not surprising to see Tarantino on this list -- his movies are like movie trivia contests with all the inside jokes and references and homages to other films.

    TV Tropes has a page about stock screams, with a heavy focus on the Wilhelm, as well.
