16. Deputy Andy Brennan
Comic relief has rarely been so adorable. Deputy Andy may well have been the goofiest law enforcement agent in Twin Peaks, not to mention the dumbest. But he also had the decency to break down and cry when Laura Palmer's body was discovered, a crucial moment in establishing the pilot episode's balance of black comedy and uncomfortable, open emotion. At times, it's as hard to imagine the show without his sweet, droopy voice as it is to imagine it without Angelo Badalamenti's score.
