Alyson Hannigan, Jason Biggs and Seann William Scott in 'American Wedding'

Unless you were studying comparative literature at Oxford or on a chain gang in Alabama, you know the first installment was centered on a handful of hyper-horny High School saps, more intent on contracting STDs than studying for their SATs. The sordid saga rolled into American Pie 2, in which the gang got together for a final summer bang before going back to wasting their parents' money in college.

American Wedding reunites prime Pie players – Jim (Jason Biggs), Jim's Dad (Eugene Levy), Michelle (Alyson Hannigan), Stiffler (Seann William Scott), and Finch (Eddie Kaye Thomas) – for the next great adventure in their lives: the eternal, permanent chaining of Jim and Michelle. And the obligatory, snafu-filled bachelor party, plus inane assortment of slap-schtick shenanigans and doggie-doo-flavored tomfoolery ensues. All leading up to the crap-happy couple finally walking down the aisle.

After witnessing a season of "CGI" sci-fi blockbusters implode creatively and at the box office, watching Jim, Stiffler and Finch's horn-ball horsing around is like getting loaded with old friends you haven't seen in years and not having to worry about them trashing your house or violating your parole.

Also keeping interest and other things up is Cadence (January Jones), Michelle's blonde babe of a sister, who forces a love triangle with jock Stiffler and intellectual over-achiever Finch (using more F-words in one scene than he has in the previous two movies). Who Cadence decides to keep time with doesn't make for great drama, but thankfully it also doesn't take many frames away from American Wedding's principle pursuits: cheap laughs and expensive lovelies. Enter the top-heavy, long-legged stripper tag team of Officer Krystal (Nikki Schieler Ziering) and Fraulein Brandi (Amanda Swisten), who in a hairpin turn of events make the pre-wedding night one the guys will never forget. Krystal and Brandi's ample assets also pleasingly provide American Wedding with the requisite raunch for the series to maintain its R-rating.

Lewd, crude and foul-mouthed, American Wedding won't win any Oscars, or teach many life lessons (except maybe never shave your testicles near a wedding cake), but for pure check-your-brains-and-pants-at-the-door rowdiness, RSVP "yes" and attend American Wedding. To borrow a tag line from Porky's (American Pie's classic teen-movie predecessor), you'll be glad you came.
