... or should I say unintentionally hilarious? Either way, this is one of the best comedies I've seen in a long time. I was laughing throughout at the antics of some of the dumbest fictional characters this side of Homer Simpson. It's just one forehead-slapping, painfully stupid scene after another as the clownish, dim-witted cardboard cutouts substituting for actual humanoid characters push, pull, and drag the "plot" to its inevitable and obvious conclusion.
If I had to describe this movie to someone, I'd call it a mutated hybrid of Fatal Attraction, Dumb and Dumber, and the Three Stooges, with a "climax" uncannily similar to the episode of Family Guy in which the whole family gets into a knock-down fistfight in the living room.
