Angry Alien Productions has a series of 30-second movies starring cartoon bunnies. Their creator calls them "movie parodies in bun-o-vision." Most of these re-makes of famous movies are quite fun. Here are some of the great scary bunny movies. There are other scary movies at the site and several other non-scary movies, but these are just the scary ones I have seen.
BTW: One friend at work does a great job of impersonating the bunny saying "sometimes" like Linda Blair in The Exorcist. She knows she'll get a chuckle out of me when she does. It's one of those gifts that keeps on giving.
