What if movies played backwards? Something Awful has an awesomely funny thread about it. My favorites:
"Titanic: An enormous iron ship surges up from the vast depths of the ocean in order to save a large number of people who are inexplicably, and somewhat foolishly, floundering in the water near an iceberg. It then kindly takes them back to Southampton."
"Jaws: A large shark finds and returns a lifeguard's bullet and oxygen tank. The shark then goes on to to rebuild a boat, and give birth to several humans through his mouth. The shark, its good deeds done, returns once more to its deep blue home -- the sea."
