As an actor, you can really play the intensity and gravity and seriousness of the moment, and just rely on the circumstances being funny. The joke is kind of the situation you're in, or the way you're reacting to something, as opposed to the characters just saying something witty.
I just know from experience that reading a funny poem aloud, especially at the beginning of a public reading, can have a certain effect. Somehow narrowing the spectrum of possible emotional reactions. So while I like it when people laugh at my poems, and I definitely enjoy being funny in them, I don't really think that's the most important thing that's going on, at least not to me.
People used to make fun of alternative comedy because sometimes it would be someone being funny, and sometimes it was a crazy man with a flute making no sense. And it's very easy to be like, yeah, that's not really comedy.
I always wanted to make strangers and friends and family laugh. I was over ten years younger than my brothers. It was hard to get attention without some kind of gimmick, like athletic stardom or being funny.
