It starts out as a men-behaving-badly skit about a couple of skirt-chasing cads who drop in on weddings to pick up susceptible girls and promptly drop them. After a frenetic montage of their modus operandi, however, the action settles into a perfectly conventional romantic comedy, hitting all the expected spots at all the expected times, as our two cads -- the equally expected Vince Vaughn and Owen Wilson, who earlier worked with the director, David Dobkin, on Clay Pigeons and Shanghai Knights respectively -- discover their true soul mates, two sisters for added convenience, a phony virgin slash nymphomaniac slash bondage girl (Isla Fisher) and a save-the-planet altruist (Rachel McAdams) who reveals her superior sensibility by giggling uncontrollably at the self-written vows of their older sister and new brother-in-law. The funny business, in what amounts merely to a newer convention, is pushed to such extremes of crassness and grossness that you feel as if the laughs are being extracted not by feather tickler but by thumbscrew. E.g., the ancient matriarch of one of America's leading political families will pepper her dinner-party conversation with epithets like "asshole," "homo" (of her own grandson), and "rug muncher" (of Eleanor Roosevelt), while her granddaughter administers a hand job beneath the tablecloth. Audiences do laugh at this sort of thing. But why? With Christopher Walken, Jane Seymour, Will Ferrell. 2005.
