The Simpsons couch gag over and over again.
Its amazing that the writers of the Simpsons can continue to keep this gag fresh over and over again. Quite an achievement. Someone with quite a bit of time on their hands have compiled a movie with every (apparently) couch gag so far.
For more “supercuts”, take a look at waxy.org. They have a great post with a very comprehensive list including every “fuck” from Scarface and every “damn it” by jack bauer! (Cheers Andy)
