This is one of the most comforting movies I know. When you get home from Dilbertland, and the world seems insane, pop this movie in and laugh at someone having it truly rough. It's cheaper than hypnotherapy.
I feel so strongly about the healing nature of this film, I will often purchase a copy and send it to a friend when they describe a particularly brain fryingly stupid day in corporate America.
And it's also a great quote movie. Watch it and the next day you'll be walking around saying, "Why should I? He's the one that sucks."
The DVD itself is light on features, but regardless, you'll want this movie on hand for emergencies. Let someone else fill out the TPS reports, and enjoy.
