“Just when I think you couldn’t possibly be any dumber, you go and do something like this… and totally redeem yourself.”

Dumb and Dumber (1994) is probably the most ridiculously, dumb, funny movie. Toilet humor at its finest, Dumb and Dumber lands on our list of the greatest movies, but does it deserve a spot? There's maybe 1 in a million odds of this movie being the greatest film of all time...so you're saying there's a chance.
