Bond takes Plenty O'Toole up to his hotel room, only to find Blofeld's goons waiting for him. One of them throws Plenty out the window after she takes her clothes off, and she lands in the pool wearing nothing but her purple high heels and her pink panties - with Plenty protesting from start to finish as her sexual humiliation is played for laughs ("I've got friends in this town!).
Bond is trapped in a pipeline with a rat, after having accidentally covering himself in Mr. Wint's perfume. James, to the rat: "Well, one of us smells like a tart's handkerchief. [sniffs] I'm afraid it's me. Sorry, old boy."
Bond using the crane to turn Blofeld's "Batho-sub" into a wrecking ball.
Blofeld: Lower! Not UP!
The transition from Slumber, Inc. to a much-needed hot bath for James Bond:
Shady Tree: Where the hell do you think you're going? James Bond: I hear that the Hotel Tropicana's quite comfortable. My condolences, gentlemen! [Morton Slumber slams the lid of the now-charred casket in disgust. Cut to Bond in the hot tub while on the phone with Felix Leiter] James Bond: Hello, Felix. Oh, very comfortable.
Earlier, before James Bond departs for Slumber, Inc. in the mortuary hearse with the waiting black suits, Felix Leiter does a courtesy inspection of the body to be burned and can't for the life of him figure out where the diamonds are. After Bond tells him, he swaps the diamonds for some convincing phonies offscreen before authorizing the delivery of the cargo to Slumber, Inc.
Felix Leiter: I give up. I know the diamonds are in the body, but where? James Bond: Alimentary, Dr. Leiter.
"You don't just kill James Bond and wait for the cops to arrive!" Of course, Bond isn't really dead - he just placed his membership card to the Playboy Club onto a smuggler he was impersonating - but Tiffany's reaction is just priceless.
For that matter, the fact a small-time smuggler would know Bond's identity is hilarious (though understandable, given he constantly introduces himself by his real name).
When Mr. Wint and Mr. Kidd trail Bond and Tiffany on the plane to Los Angeles, the latter quips "I must say, Miss Case seems quite attractive... for a lady." Wint turns to Kidd and gives a humorously disapproving look.
The "brother" scene, as James Bond, disguised as Mr. Franks, is taken to Slumber, Inc. by black suits under the employ of its funeral director, Morton Slumber.
Hearse Driver: The, uh, stiff... [clears throat] the deceased back there... your brother, Mr. Franks? James Bond: Yes. He was. Random Black Suit: I've got a brother! [Beat] James Bond: [smiling] Small world.
This subtle gem as Mr. Wint and Mr. Kidd prepare their final attempt to kill an unsuspecting Bond and Tiffany with dinner aboard the cruise ship.
Not to mention the clever method by which Bond smokes out the two assassins at the dinner service.
Bond: The wine is quite excellent. Though for such a grand meal, I'd have rather expected a claret.
Mr. Wint: Of course, sir. Unfortunately, our cellar is rather poorly stocked with clarets.
Bond: Mouton Rotheschild is a claret. (Mr. Wint adjusts his bowtie)' And I've smelled that aftershave before, and both times, I've smelled a rat.
While Bond is getting his briefing, he delivers a typical critique on the quality of the brandy being served - when he professes little knowledge on diamonds, M snorts "Refreshing to hear that there is one subject you're not an expert on!"
