The language of comedy is violent: “I really killed up there.” “I knocked ’em dead.”

When comedy fails, the comedian says, “I died up there.” “I was really bombing.”

It’s a matter of force: “I MADE them laugh.”

Comedy provokes a physical, literally visceral reaction; “gut-busting” comedy will make you (in the words of TV’s old Felix the Cat cartoon) “laugh so hard, your sides will ache.”

Comedy: not a profession for wimps.
