"Edith's 50th Birthday": As Edith is about to get raped by the man who broke into her house, she panics when she realizes she left her cake in the oven. She and the rapist rush into the kitchen, Edith takes the burnt cake out, and slams it in the guy's face before running out of the house.
Perhaps the greatest-ever CMOA on the part of a Studio Audience, who immediately fill the studio with deafening cheers once Edith evades her would-be rapist, even stamping their feet on the bleachers. All by itself, it elevates the scene from great to unforgettable.
And in the second part of the episode, both Gloria and Edith get crowning moments. Gloria calls her mother out on why she refuses to testify against the rapist, getting increasingly angry before finally screaming, "You're not my mother anymore!" Edith, in response, slaps her across the face, breaks down, and then confidently walks towards the front door.
"Come on, Archie."
STIFLE! - Edith Bunker
"Archie and the KKK". An episode in which Archie is invited to join a meeting of the local chapter of a group which seems to share his political and social beliefs. Upon discovering that this group is, in fact, the local branch of the Ku Klux Klan, and that they intend to set a cross alight on Mike's lawn, he tries several gambits to get them to change their minds. Finally, he pulls out a card nobody would have ever seen coming from him:
Klansman 1: There's a whole lot of us, Bunker.
Archie: Well, lemme tell you, there's a whole lot of us.
Klansman 1: Us who?
Archie: Us blacks!
Klansman 2: Whaddaya talkin' about?
Archie: I'm talkin' about my gall bladder operation last year, when I had to take one of them transflusions there, they put me full of blood!
Klansman 2: What blood?
Archie: Black blood, buddy! A whole lot of it! I think, enough to fill up a six-pack!
Klansman 1: So that's what's wrong with ya.
Archie: Nothin' wrong with me, hey, I notice I sing and dance better! But, the main thing that does to me, see, that gives me the right to call out a whole gang of my black blood brothers, to come with me and back me up, see? And if we catch youse guys burnin' any crosses, we're gonna come up here, and we're gonna bust your honky heinies!
Mike giving a raspberry to God. Archie can only say "WOW!"
"The Draft Dodger," the seventh-season Christmas episode where the Bunkers host Mike's friend, David Brewster (a draft dodger) and Archie's buddy, Pinky Peterson (whose son died in the Vietnam War), earns its star when – after Archie went on an angry rant against draft dodgers – Pinky (the "Gold Star father," as Archie calls him) diffuses the explosive situation by calmly telling how he wishes his son could be there right now, enjoying Christmas dinner. He goes on to explain he held the same opinions about the Vietnam War as Archie did … until his son was killed in action, then develops an unlikely friendship with Brewster. Pinky's impassioned speech – which ends with him wishing Brewster a merry Christmas and a handshake – was one where you could hear a pin drop. Prior to everything unfolding, Edith, Mike and Gloria (who are in the know from the start) try to conceal the truth about Brewster from Archie.
The second half of "Cousin Liz" qualifies both in-universe and for the series as a whole. Archie and Edith attend the funeral of Edith's cousin Liz, where they meet Liz's long-time roommate, Veronica. Liz has left Edith a valuable antique tea set (worth at least $2,000), but Veronica asks Edith if she might let her have it. When Edith asks why, Veronica, in very stilted terms, reveals the truth about her relationship with Liz—they were deeply in love with each other. Edith gets several Crowning Moments in the scene: she immediately accepts Veronica's love as legitimate, remarking that she wishes Veronica hadn't told her about the situation—not because she disapproves, but because it deeply saddens her to realize that Veronica has lost the love of her life. Edith also tells Veronica that she can certainly have the tea set, as she is Liz's true next of kin (to put this in perspective, arguments are still being made in 2014 about property laws for same-sex couples).
Later, when Edith tells Archie the truth, he is completely stunned, but still insists on keeping the set. Edith firmly tells him "No," and outright declares that she is "disobeying her husband." When Archie threatens legal action, Veronica panics—she works at a school (as did Liz), and the public revelation of her sexuality would cost her her job. Archie realizes this, but still plans on going through with a lawsuit. This leads to an exchange that convinces Archie to let Veronica keep the tea set; this argument, despite being almost forty years old, sounds remarkably familiar:
Archie: Who the hell wants people like that teachin' our kids? I'm sure God don't! God sittin' in judgment—
Edith: Well sure he is, but he's God! You ain't!...She can't help how she feels. She didn't hurt you, so why should you wanna hurt her?
Finally, this episode aired in 1977, when it was considered taboo to even mention gay people on television, let alone present them as being in long-term relationships. Barry Harman, one of the episode's writers, pointed out that a rerun of the episode aired the night before Californians voted on a law that would have barred homosexual individuals from working in public schools; the law was not passed, and Harman suggested that the message of the episode may have had something to do with it.
