National Lampoon's Animal House
Okay, okay, we know there's a lot of National Lampoon on this list, but for good reason: nobody does vulgar, raunchy and wild in quite the same way. If you're only going to watch one of these movies, Animal House should be the one. Unlike Van Wilder and Spring Break, which fall in the so-bad-they're-good category, Animal House is—wait for it—actually good. This 1978 classic will have you ready for rush week in no time flat.
