Okay so, got here from a book on animal behavior but: Vulcan stand-up comedy as a competitive activity.
Because most Vulcans don't actually pretend they don't have emotions, it's all about self-regulation, right? And good comedy usually hinges on manipulating the relationship between our faculties of recognition and surprise in various ways, you can get pretty scientific with it.
So Vulcans go to the comedy act, and the idea is the comedian is trying to make you crack up, and the audience is trying to not even crack a smile, and if you do laugh, you lose. Like all in good fun, but Vulcans are both really competitive and really aware of how dangerous that urge can be to a society, so this could actually be classified as highly orthodox Surakian practice.
So of course the comedian has to actually be funny, or there's no challenge and the game is boring.
Which means the really good Vulcan comedians (most of whom tend to extremely dry delivery of their bits) are going to go around playing to packed houses, which mostly sit staring stonily back at them, with occasional breaks when someone loses it and reacts.
And after a show you'll have Vulcans walking out discussing with great approval how very humorous that was, with varying degrees of muted smugness or chagrin depending on if they won or lost.
I bet there are human comedians whose grandest fantasy is being good enough to do a set in Vulcana Regatta and have people going around bragging about not laughing at them.
