Patsy: Well, sir...I'm a Jew.
Arthur: ...Well, why on earth didn't you say so, Patsy?
Patsy: I'm sorry, sir, but...it's just not the sort of thing you tell a heavily-armed Christian.
- "I'm All Alone". Arthur singing about how alone he is? Sad. Patsy standing right there? Really sad. A bunch of other knights joining in Arthur's lament of how alone he is? Priceless.
- The Reveal of the Lady of the Lake's true identity.
Arthur: Lady...I would have your true name.
Lancelot: ...Holy shit.
- His name is Lance-a-lot, and in tight pants-a-lot!
Arthur: I thought you were a fairy.
Lady of the Lake: No, that's Lancelot.
- "The Song That Goes Like This." Each time the Lady of the Lake and Galahad try to bring the song to a close, the key just modulates again. By the final chorus, they're screaming "Oh, GODDAMMIT!" at the orchestra.
- The battle between King Arthur and the Black Knight is 100% pure hilarity.
- "It's only a flesh wound!"
- "You stupid bastard, you've got no arms!"
- In the touring production, at least, they distract the audience from setting up the "legless" special effect by having a man come on asking for "a'msnote for the poor"
- In "You Won't Succeed on Broadway", Sir Robin, his Minstrels and the Knight Chorus re-enact the Bottle Dance scene from Fiddler on the Roof... with grails on their heads. Robin's first mention of "if we don't have any Jews" is usually met with a full minute of laughter as well.
