Bond asks who would pay a million dollars to have him killed. Quoth M: "Jealous husbands, outraged chefs, humiliated tailors. The list is endless!"
Bond asking Miss Goodnight, who's in a bikini, "Don't you think you're a little overdressed?"
Bond accidentally swallowing a spent Scaramanga bullet he was retrieving during a fight and requesting that a taxi take him to "the nearest pharmacy" afterward.
Andrea trying to explain what Scaramanga looks like so Bond can find him at Bottoms Up, and after struggling to come up with a distinctive feature she mentions his third nipple.
Bond: Fascinating anatomical tidbit. But probably the most useless piece of information I've ever heard. Unless, of course, the Bottoms Up is a strip club.....and Scaramanga is performing.
After Scaramanga makes his getaway in his flying car:
M: So if I understand it, Scaramanga got away - in a car that sprouted wings!
Q: Oh, that's perfectly feasible, sir. In fact, we're working on one now.
M: Oh, shut up, Q!
Nick Nack giving a "So long, sucker!" look to Bond during the car chase scene. Made funnier with the look of amused contentment on Scaramanga's face.
