You can practically smell the party emanating from John Belushi. On the dance floor, he gyrates in the comfort of his roomy toga, pizza-fattened limbs and unkempt hair a-flying. And the way Bluto opens the hatch to down an entire bottle of Jack Daniels puts him in a league of his own (not that you should emulate the feat).

With his face in a constant expression of mischief, Seann William Scott exudes a never-ending excitement for all things depraved: His type of partying technique involves slipping a friend a laxative and bragging about notches on the old bedpost. The marrying type? Nah, but he's more than happy to organize your bachelor party.
