A masterpiece of hilarity in both acting and writing, I can't think of a comedy as creatively and deliriously entertaining as this. It is hysterical in how it knows exactly what buttons to push, especially in the dark comedy realm. The concept itself is brilliant: a humorless serial killer kidnaps two stand-up comedians and forces them to teach him how to develop a sense of humor. The rewatch value is limitless and is at least on par with "Groundhog's Day." It's a shame that so many people have no idea what they're missing out on. I can't wait to see it again.
