Bottom (1991)

Rik Mayall and Adrian Edmondson wrote it and star as Richie Richard and Eddie Hitler, two broke, anti-social and regularly violent losers stuck in a squalid Hammersmith apartment. This is slapstick pushed to cartoon extremes, where the punchline is usually somebody getting hurt. It isn't subtle and never tries to be, which is exactly why it has such a loyal following. Pick it when you want a double act at full volume, and skip it if pain-as-comedy leaves you cold.
