Warning: Do NOT click the link below unless you have seen BOTH Toy Story 2 and Requiem for a Dream. Otherwise, it might spoil both movies for you.
Have you ever heard of a trailer mash-up? It's where they take the audio from one movie and the video from another to make it totally different. They sometimes just re-cut one movie to put a completely different spin on it (there was a great family comedy version of "The Shining" out there a while ago.) Well, this one has video clips from Toy Story 2 and sound from Requiem for a Dream. It's probably the most well-done I've seen yet - both scary and hysterical. The audio matches their lips too! NSFW for language reasons.
