For example, I don't like it when people say they are in any form of comedy (Sketch, Improv, Stand-up) because they "Like making people laugh." That can be a side reason, sure. We're all a bunch of insecure jokesters who want that sweet sweet laughter to make us feel important and in control. "Ha, I got that laugh out of you." But my point is that anyone who has the sole drive of making people laugh is going to, at one point or another, ruin a perfectly good laughless scene because they don't hear that laughter. God forbid you make people feel an emotion or create something that's funny in a manner other than laughing out loud. Or a line that doesn't quite sing and put the audience in stitches, guess I should go for the easy laugh by hitting myself in the nuts and saying something in a funny accent.
Personally, I like comedy because it touches every facet of the human experience. Even unfunny people use jokes to say things that they're too awkward to be direct about. Comedy is an artform to tell people truths they don't want to think about when they're in a bad mood. So you put them in a good mood but also get them thinking about that thing they don't want to think about. They see your opinion on the matter, they had a good laugh, but (hopefully) they don't walk out thinking "Oh man, did you hear that guy talk after he got hit in the nuts?"
I don't think every scene has to have a message to it, but I think our characters can have informed opinions and be real people with voices that want to be heard, rather than vehicles for some dumb joke. And for all you laugh-whores out there, remember: You'll never achieve a better reaction than a video of a laughing baby.
Why did you get into comedy?
