Dumb & Dumberer: When Harry Met Lloyd (2003)
I actually think it's a bit better than it was given credit for back in the day. The performances are pretty amusing. The guy doing his best Jim Carrey impression is pretty entertaining. And it still has some amusing lines here and there. Worth revisiting. Although they should have had something about their worm store... haha
Dumb & Dumber (1994)
Still gold.
