Lesson Learned: You're never too old to party with drunken freshman chicks—well, at least not in the movies.

College students hear it all the time: “Enjoy school while it lasts, because it's all downhill from there.” For people stuck in desk jobs straight out of Office Space, that's a sad truth. Along with nine-to-five commitments come marriage, kids, diminishing amounts of sex, and, well…need we say more? In director Todd Phillips' Old School, though, middle-aged dudes get their chance to relive the good old days of house parties, beer funnels, and horny co-eds. It's fantasy porn for married men.

It's also Phillips' best movie to date—yes, The Hangover included. Old School solidified both Will Ferrell and Vince Vaughn as titans of lowbrow comedy; as for star Luke Wilson, let's just congratulate him for not boring us to tears for a change. They play three working-class friends who launch a half-assed fraternity after Wilson's character moves into a house on the outskirts of a university's campus, which, naturally, brings forth underaged hook-ups and other forms of debauchery. And it remains hilarious no matter how many times you've seen it.
