Although ostensibly concerned with the sacred union between band camper Michelle (Alyson Hannigan) and nervous nelly Jim (Jason Biggs), American Wedding, the third movie in the American Pie franchise, belongs to the obnoxious, self-centered Stifler (Seann William Scott). The self-proclaimed "Stifmeister" generates most of this movie's laughs with antics including but not limited to ingesting feces and engaging in coitus with a senior citizen. The plot: Stifler finds out he's not invited to the titular ceremony, weasels himself onto the guest list, and hits on the bride's younger sister, Cadence (January Jones). That's about it--but it's enough of a springboard for the hypermacho Stifler to get embroiled in any number of amusing situations that impugn the magnitude and certitude of his heterosexuality (including a priceless '80s music dance-off in a gay bar). It's easy to hate these movies, but it's equally easy to laugh, if you're willing to dig into the material on a Farrelly Brothers maturity level. Besides, Scott's consistent willingness to playfully undermine the stock jock archetype represents some sort of social progress for the generally reactionary teen-comedy genre. A welcome bonus: hearty roles for both Eugene Levy and Fred Willard.
