The more I think about the scene in The Young Ones where they write a letter to the bank manager, the more I think it’s one of the best scenes in the whole series. Let’s have a look at it.
So what makes it so good?
It barely advances the plot, but it does do a lot of exposition work, expertly hidden. Everything a character says is funny, but more importantly, those lines come from that character’s perspective. None of those jokes would fit in other people’s mouths. That’s good writing, and that writing informs even better performances. There’s conflict, but not the bickering kind, and it reaches a satisfying punchline.
I wonder if it might be a good exercise when developing your own characters to re-create this scene with them, and see how the letter ends up. Could be fun, and enlightening.
