Lloyd and Harry may be two of the dumbest characters to ever grace the cinema screen, but such is their ignorance and naivety that their traits just add to their eternal charm. The Farrelly Brothers directed classic may be getting on a bit now, but it's no less funny than the day it was released. Oblivious to the fact that the briefcase that they're trying to return to a woman in Aspen is full of ransom money, the two embark on a road trip to return the cash to its rightful owner, only to be constantly hounded by the crooks that it was meant for. They may be inseparable best friends, but the duo constantly play pranks on each other to try and win the affection of their mystery woman. Lloyd spiking Harry's drink with laxatives is one of the most famous scenes, but the two are so dimwitted that they more often than not are the architects of their own demise: Harry getting his tongue stuck to a chair lift at a Ski resort being a particularly fond memory. Regardless of their competitive natures, both idiots always make amends, and while they won't be getting into Mensa any time soon, you can be sure that the two will always be friends, accompanying each other in their shared idiocy.
