Mark Rahner, Seattle Times interviews Steve Wright:

“Q: Do you work hard to craft a joke about, say, sh**ting a mime with a silencer?

A: I just hang out. I just go around and do stuff, and something’ll hit me. I write some stuff down. I don’t know what I do. I just look around and walk around aimlessly.

They just come into my mind and I just write them down. I can’t write them on purpose. I don’t think, “All right, today I’m going to write some jokes.”
