Tear Jerker: The Young Ones
The end of The Young Ones. Yes, it's supposed to be funny, and they were all little rotten bastards... but it's just so sad, especially after they finally got the freedom they wanted (that's probably the point). And that sad "doo-wop" music that plays over the credits makes it so... poignant.
The credits. Many filmmakers have said that filmmaking is a group effort, that it's never one man's film, but it doesn't change the fact that the people who say this are usually the guys who are listed first in the end credits. But during The Young Ones finale, the credits start, and there's no mention of who did what—everyone's listed alphabetically, regardless of their part on the program. For that one moment, while the program's in its death throws, everyone's equal. Even on a show about complete bastards blowing each other up and screwing each other over, there's something rather touching and poignant about that.
Same episode, the scene prior: Vyvyan accidentally running the Vyvmobile into a lamppost and realizing he had also unwittingly killed SPG, who was asleep on the radiator. His car and his hamster were the only two things he ever showed anything resembling affection toward, and he is absolutely crushed to lose them both — the only indication he ever gives on the series that he has a heart. Granted, he’s forgotten all about it a few minutes later, but still.
