Raunchy, easygoing frat boy entertainment that could only have come from the 1980s. Crammed with all the hallmarks of party films from that decade - glaring fashion choices, oodles of saxophone, frequent gratuitous nudity and tons of recreational drugs - it's wafer-thin and proud. The title pretty much tells you all you'll need to know about the plot, which frees up the rest of its running time to go nuts with blasphemous humor and increasingly inebriated acts of questionable legal standing. It's a perfect fit alongside the wild-eyed greats of its generation; Caddyshack, Animal House and Revenge of the Nerds, make some room. Tom Hanks sometimes presses too hard to look crazy, unruly and cool, and often leaves us wondering how anyone could agree to marry such a slob (this may be the first time I've ever agreed with the pensive father-of-the-bride in this kind of movie), but when the music starts blaring he makes for a great master of ceremonies and that's really what the role called for. Pointed and unpredictable, balls-out and funny as hell, it's fantastic at what it sets out to do.
