It's very, very corrupting to the spirit, doing comedy. And you have to be almost a saint, like Jack Benny was, like Steve Martin is, to avoid the corrupting of it, because there's very little work where the actual work and the reward are simultaneous, and comedy is that.
Stand-up comedy is a very hard thing on the spirit. There are people who transcend it, like Jack Benny and Steve Martin, but in its essence, it's soul-destroying. It tends to turn people into control freaks.
