Tonight's Brief But Spectacular pulls back the curtain of the NBC show Late Night With Seth Meyers.Amber Ruffin and Jenny Hagel write for the show and perform regularly in the long-running Jokes Seth Can't Tell segment.The writers, funny comedians in their own right, give us a sense of what it takes to get a joke on the air.This segment is part of our ongoing Canvas series on arts and culture.When you hear a joke that you know is the perfect joke, first of all, usually, that happens to me when it is someone else's joke.Yeah. I feel like comedy writers rarely even laugh.When a comedy writer hears a joke that good, they all go, oh. Oh, you did it. You got it.When I first started writing Late Night With Seth Meyers, I was trying very hard to kind of figure out Seth's voice.And there happened to be an item in the news that was about lesbians, and I don't remember what it was, but I happen to be a lesbian.So, I saw that headline and I was like, here we go.And I think I submitted like 10 jokes about that.And then I saw the head writer, Alex Baze, in the hallway later and, just jokingly, I was like, Let me know if you need more lesbian jokes.And he was like, We cannot use them. And I didn't, I just hadn't thought about that.Like, right, Seth can't burn lesbians. I pulled Amber aside.And I said: Hey, what if we tried to do a segment where we tell jokes that Seth can't tell?And Amber was like, Let's figure that out.In Jokes Seth Can't Tell, Seth sets up the joke, and then the minority says the punchline. Yes.
