Every season of Dumb and Dumber ever, ranked from best to worst by thousands of votes from fans of the show. The best seasons of Dumb and Dumber!

The mind-blowing adventures of America's favorite morons take a surreal turn in this cartoon spin-off of the smash success comedy movie Dumb and Dumber. The show starts off with the duo rescuing their dognapped van, Otto, and picking up one strange pet, Kitty, a purple beaver, then hits the road for the ridiculous with the pedal to the metal. No circumstance is to strange for this show's satire, from the mundanities of physical fitness and test piloting to the insanities of robot mailmen and speeding taco-mobiles rigged with stink bombs!
