I'm not a big fan of the "long set" in comedy. Guys like to go on, like to do an hour and 45 minutes. The audience will win if you stay out there too long! [...] I want to go out. I want to get you down. I want to beat the snot out of you and get out of there before you realize that I... beat the odds!

Comedy -- and show business -- is-- look: either I win, or you win. There's no truce! Same thing with television: I knew that [Seinfeld]-- I knew-- look: either you're gonna kill me, or I'm gonna kill you. And after nine years, I was still killin' that series, but that series would eventually have killed me.

The first thing I want to do [on stage] is: I want you to have confidence in me. Well, how am I gonna do that? I'm gonna take the joke that fails the least amount of [the] time, and I'm gonna put that at the front of the set. It's just tech-- it's scientific technique. [...] If the first thing I say gets a laugh: at that moment, 100% of everything I've said gets a laugh! And now, I've got your confidence.

[Stand-up is] a martial art. It's voice, it's action, it's gesture; and everything is synchronized to land on that [weakest] point. You ever watch these karate guys? They hit that brick: it's a perfect arrow that hits that target, and when it-- and it's perfect! It's a concentration of energy. And that's what elicits the laugh.

The specific element that occurs in every single successful joke is surprise. Surprise. A line of logic is going one way, and then, it doesn't. I call it "making non-sense". You go "That doesn't make any sense, but I get it." That-- That's the words that people use to describe a joke: "I got it."

That's the first thing an audience wants to feel when someone gets up on a stage: "Does this person know what they're doing?" "'Cause if they do, then I can relax." And when you're trying to elicit laughter, that's-- they have to be relaxed. If they're worried about you, the laughs are harder to get.

We worked to death. Y'know? That's what Larry and I did. We did not rest, we did not... spare an ounce of effort; we would just order people out of the room: "Get out! Get out! We're working!" Y'know? And we-- And that's why those scripts were as good as they were: 'cause when they got to that table, and those actors got 'em, they were worked. So: is that luck? I don't think so. That wasn't luck. That was-- We earned that.

There was [an] incredible amount of luck -- good luck -- that I had, that made [Seinfeld] what it was. On the other hand, I could argue against that. I could say "I'm the one who said to Larry David: 'Y'know, when you and I talk, it's really funny. We should write something together'."

Nobody goes berserk eating in the morning. You never wake up in the morning and eat a decent breakfast, and then attack a box of brownies. You don't do it. But at night, we all do it! Why? We're tired. And when you're tired, your willpower goes away. Willpower requires energy.
