Dumb and Dumber (1994)
The title of this movie pretty much sums it up. Jim Carrey and Jeff Daniels acting like idiots for an hour and a half. But with Daniels and especially Carrey, it works. He just acts silly and knows how to do it well. Daniels is good for relief of Carrey, and knows how to deliver lines, but isn't really on Carrey's level. And there are plenty of sophomoric jokes that really don't belong in the film. But who cares? I wanna see Jim Carrey! "Wanna hear the most annoying sound in the world?" "Out with the bad and in with the good!" "Let's put another shrimp on the barbee"
