The audience still won't laugh at a joke unless they think it's funny. I know that because I try out new jokes within my show, I slip some in here and there, and ever since the beginning, I've had a one-in-five, or one-in-four ratio. For every four or five I write, one will be good enough to stay in the act, and that's still true even now.
