The conclusion is also a CMOA, in which Diane reveals that the two men the gang hustled out of Cheers were not gay, and that the two gay men she said were in the bar were still there, and had a ball watching the gang behave like morons the entire time. She says as she walks away, "Isn't that right, guys?", and two of the regulars kiss Norm on the cheek.
To his credit, Norm concedes defeat—as only Norm can:
Norm:(pointing at the regular on his right) Better than Vera.
Coach, of all people, helping Harry with a Kansas City Shuffle to win all of Coach's poker winnings back from another con man. This made Harry the Hat a likeable Ensemble Darkhorse, instead of the seedy con man he could have been.
Cliff has read that his medication can cause male breast enlargement:
Cliff: I see you all looking at my chestal area; stop it! I don't have breasts!
Rebecca: Don't let them get to you, Cliff. I took that medication and the risk of side effects is very overrated.
Cliff: Oh, yeah, Rebecca? How long ago did you take it?
Rebecca: About twenty years ago; back when I was a little boy.
In the episode "Sam's Women," Sam thinks Diane thinks that the only women Sam can get are all stupid. Diane asserts that an intelligent woman would never fall for his lines. They argue about it (and insult each other), and finally apologize. Then they have this conversation:
Sam: Well I'll be darned.
Sam: Nothing, I just... noticed something.
Sam: Well I guess I've never, uh, never looked into your eyes.
Diane: Something wrong with them?
Sam: No, I, ah... I just don't think I've seen eyes that color before. As a matter of fact, I don't think I've ever seen that color before. [Shakes head] Yes I have, yes I have...
Sam: I was, ah, I was on a ski weekend, up at Stowe. I was coming in late one day, last person off the slope. The sun had just gone down... And the sky became this incredible color. I, I usually don't notice things like that. I found myself kind of walking around in the cold, hoping it wouldn't change. Wishing that I had somebody there to share it with. Afterwards I tried to convince myself that I'd imagined that color, that I hadn't really seen it, that... nothing on this earth could be that beautiful. Now I see I was wrong.
[Diane stares at him silently, near tears]
Sam: Wouldn't work, huh?
Sam: An intelligent woman would see right through that.
Diane:(Sadly) Oh— (covering loudly)OH...! In a minute!
Made funnier by Diane turning, grabbing one of the drinks on her tray and gulping it down.
Diane gets in a vicious one during their breakup at the end of Season 2.
Diane: Do you know what the difference between you and a fat, braying ass is?
Diane: The fat, braying ass would. (oh, snap!)
Frasier's speech to Sam and Diane in the ending sequence of "Triangle":
This was to be Kelsey Grammer's exit after fulfilling his 8 episode contract, but the producers decided Frasier Crane was too good of a character to throw away, and thus, 19 more years of Frasier Crane ensued in one form or another.
The final sequence of "Chambers vs. Malone". After Sam proposes to Diane in court (It Makes Sense in Context...), Diane apologizes for putting him through the whole ordeal—and then promises not to hold him to the proposal. She then begins to leave—but...
Sam:Where are you going...? (Diane stops; turns to him as he rises) Y'know, you're not gonna get off that easy—y'know, you're gonna pay for what you put me through.
Diane: ...What do you mean...?
Sam: I proposed to you...you said "yes". Now they can stop me from killing you...but they can't stop me from marrying you.
(Pause. Diane stares at him. Sam smiles, beckoning with his finger.)
