"The Crimson Permanent Assurance" for Mind Screwing the audience by playing right before the main feature, and then returning to attack the film itself halfway through.
The way the movie decides to deal with the Crimson Permanent Assurance's attempt to intrude on the feature presentation: tipping over a skyscraper onto it.
Really, that entire goddamned short in all of its epic, unparalleled absurdity. A bunch of old British men become pirates and sail a building all the way to America.
The "liver removal" sceneCrosses the Line Twice between shockingly gruesome and absolutely hilarious, especially with "The Galaxy Song" coming right afterwards. As does the Mr. Creosote scene. But the capper is the very long Steadicam shot where Eric Idle's waiter takes us for a little ride, then launches into a Cluster F-Bomb rant.
