Jim (Jason Biggs) gets a blow job under a restaurant table from Michelle (Alyson Hannigan), the girl he’s going to marry. Stifler (Seann William Scott) swallows dog shit and pretends it’s chocolate. Finch (Eddie Kaye Thomas) gets it on again with Stifler’s mom (Jennifer Coolidge). Pubic hair winds up in the wedding cake. I don’t care that Jesse Dylan (Bob’s son) directed it, or that it grossed $34 million on opening weekend — this third hunk of Pie is a worn-out gross-out, a remnant of a genre that now seems so five minutes ago.
