Stand up comedy is this thing you get to do, so you have to treat it with respect. You can't just be like, 'Alright, I got my hour down, people are coming to see me now. Now, I'm going to lean on the mike stand.' No, you gotta work even harder now. You got to top what you already did. Because they'll find someone else.
Acting in a sitcom or a comedy movie is like a comedy routine with the setups.
