We know, via the last episode, that they marry and divorce.
A touch of poignancy?
Dude, she tells him he’s an asshole! 
The future portrayed in All Good Things… was an alternate timeline.
I don’t agree that it was even that, though it certainly was not the definite future of the Enterprise-D crew; it directly contradicts everything from after the first TNG movie. At any rate, I think the future Picard saw in the series finale was no more than a hallucination or illusion arranged by Q. It is self-contradictory otherwise.
I don’t remember the future shown in All Good Things… being so wildly different that it would be a hallucination or illusion. The Federation’s non-existence in The City on the Edge of Forever, the Klingon-Federation war in Yesterday’s Enterprise, the Klingon-Cardassian Union in the *Crossover * et al, the year of hell in Year of Hell, and the temporal clusterfuck that was *Enterprise *were all more extreme in their divergence than it was and they’re all accepted as alternate timelines or parallel universes.
Was there even anything in All Good Things… that directly contradicted Generations? If not, the point of divergence could have been as simple as the Enterprise-D not being destroyed in orbit of Veridian III.
Don’t forget this classic:
Smithers: I’ve always loved you, sir.
Burns: Well, Smithers, thanks for making my last moments on Earth socially awkward.
And there’s the final minutes of the final episode of Black Adder. Not recommended for those looking for a few laughs.
We’ll go to Australia. They speak English there. And the banks are easy.
There was a TV series on the Holocaust about 20 years ago, and two of the characters, a doctor and his former patient, are being led to their execution. The doctor says he always thought his companion was a good patient. The patient responds by saying something like thank you, I always tried to follow your advice, watched my diet, etc. The doctor cuts him off and says “No, I meant you always paid your bill on tme.”
Bad, just due to cheese factor:
“Flash, Flash I love you! But we only have 14 hours to save the Earth!”
On Get Smart Agent 86 proposed to Agent 99 when he thought they were both about to be killed by the bad guys. Afterwards he wanted to just forget the whole thing, since they had survived, but 99 believed the proposal and accepted it, so they ended up getting married.
99: Max, you called me Earnestine!
86: I know. I, uh…
99: Too bad that’s not my name!
I love when Melanie is on her deathbed and Scarlett finally realizes that she loves her. Melanie was the only true friend she ever had.
Return of the King
**Frodo plops down on the rock and lies on his back.]
Frodo: I can see the Shire, the Brandywine River. Bag End. Gandalf’s fireworks, the lights in the Party Tree.
Sam: Rosie Cotton dancing. She had ribbons in her hair. If ever I was to marry someone, it would have been her. [He cries.]
It would have been her!
[Frodo puts his arms around Sam and holds him close, dripping tears.]
Frodo: I’m glad to be with you, Samwise Gamgee, here at the end of all things.**
Then they make out.
Just kidding!
I almost teared at that.
The Man Who Would Be King:-
“Peachy, I’m heartily ashamed for gettin’ you killed instead of going home rich like you deserved to, on account of me bein’ so bleedin’ high and bloody mighty. Can you forgive me?”
“That I can and that I do, Danny, free and full and without let or hindrance.”
“Everything’s all right then.”
Airplane!
“I’ve never been with a horse before . . .”
Hah. From Vasquez, it’s a term of endearment. I liked the way they clinked their grenades together after they pulled the pins.
I don’t remember them clinking the grenades together; I just remember them wrapping their hands around each other on the same grenade.
And, and I should add, a favorite such scene. The two characters who are to be executed at the end of Breaker Morant silently hold hands as they’re walking out on the field. Just before the fatal volley, Morant shouts to the firing squad, “Shoot straight, you bastards! Don’t make a mess of it!”
Gah! I was JUST NOW coming to post that one! More poignant to realize that, to Morant, up until that point, everything his judge, jury, and executioners had done was a ‘mess’.
