OK forget the plot. It's irrelevant. The only reason anyone will go see this is for the poo and fart jokes, and there are plenty of those. What no one expects is the fact that the writers actually come up with some wonderfully comic moments, and they fill the script with genuinely witty one-liners between the unfunny low-brow stuff. And the cast is better than you expect as well. Besides Olsen and Richardson eerily channelling Jim Carrey and Jeff Daniels (as well as creating their own, more sympathetic versions of the characters), Oteri is hilarious as the sassy-but-dim conniver. And as with almost every film he's made, Levy is the funniest thing here, creating yet another memorably evil cinematic principal. And perhaps the nicest surprise is that this film stands completely on its own as a sweet and likeable teen comedy--albeit a very stupid one! All it lacks is the Carrey/Daniels star power. But it's far funnier than most bigger-name comedies out there at the moment.
