‘Dumb and Dumber 2′ Stars Jim Carrey and Jeff Daniels Nap, Talk Sequel on ‘Tonight Show’

'Dumb and Dumber 2' (officially titled 'Dumb and Dumber To') might not be hitting theaters until November (you've already waited 20 years to see it, you can hold out a few more months), but stars Jim Carrey and Jeff Daniels are already hard at work on the promo trail.

The duo kicked things off last night with a long visit to 'The Tonight Show,' where they debuted the first 'Dumb and Dumber 2' trailer and covered a bevy of topics, like what the first day back on set together was like, the Canadian soap opera in which they starred with host Jimmy Fallon, fake arms, naps -- and yes, you read all that correctly.

Minced into an interesting interview about the production of the pair's next opus, Fallon and the guys also reminisced about their fake-armed Canadian career, Carrey's need for a nap, and we think something about lettuce. This one has it all.
