The Screwtape Letters/Funny


 * When Screwtape gets worked up about the difference between Heaven and Hell, to the degree that he involuntary takes the form of a large centipede. It becomes even funnier when read by John Cleese, who had to pick bits of studio from between his teeth after that particular take.
 * In the play version, Screwtape points out that famous people are a "good" influence, since they're always changing their minds...then tilts the book he's reading to reveal that it's a biography of Madonna. Cue "Material Girl" playing during the next set change.
