I agree. Everything before the "fucking Catalonia Wine Mixer" was hilarious. If you have the dvd, check the deleted scenes for the night-vision speech. Best part of the movie and they cut it out.
So far I've seen it twice and both times I laughed pretty good. John C. Reilly's speech protesting the move in about making your own beef jerky and what not is hilarious. The father (just looked it up) Richard Jenkins, the father in six feet under, was hilarious also....
