30-Second Bunnies -- Bunnies recreate famous movies in 30 seconds. Not to be confused with Bunny Suicides, which are rather amusing, if you have a black-as-night sense of humor like me. Also not to be confused with Greg the Bunny, which is kind of X-rated Muppets (and also very funny, and occasionally sacrilegious).
