Superbad

Seth (Jonah Hill) and Evan (Michael Cera) want nothing more than to lose their virginity before they head off to college.
To do that, though, they need to get liquor for the big party that night. With the help of their friend Fogell, a.k.a. McLovin (Christopher Mintz-Plasse), and his fake I.D., the three of them go on a hilarious chase for that elusive booze, dodging incompetent cops, angry neighbors, and jealous boyfriends.
