Larry and I were so good together [on Seinfeld], if we both thought something was funny, that was good enough. That's it. If it can get through those… - Jerry Seinfeld

[Seinfeld] was gonna be a 90-minute special that was gonna fill in for Saturday Night Live one weekend-- one Saturday night when they were off. [...] And I just didn't think that you could sustain that for 90 minutes. I thought maybe you could do it for 30 minutes. And that's how it became a TV series. It was gonna be a special all the way, but I just didn't think we could last 90 minutes. So, instead, we ended up makin' 90 hours.

There are many things we can point to as proof that the human being is not smart. The helmet is my personal favorite: the fact that we had to invent the helmet. Now, why did we invent the helmet? Well, because we were participating in many activities that were crackin' our heads. We looked at the situation. We chose not to avoid these activities, but to just make little plastic hats so that we can continue our head-crackin' lifestyles. The only thing dumber than the helmet is the helmet law, the point of which is to protect a brain that is functioning so poorly, it's not even tryin' to stop the cracking of the head that it's in!

I chose comedy because I thought it seemed much easier than work. And more fun than work. It turned out to be much harder than work, and not easy at all. But you still don't have to ever really grow up. And that's the best thing of all.
