[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. [...]… - Jerry Seinfeld

I was happy with the Seinfeld finale because we didn't want to do another episode as much as we wanted to have everybody come back to the show we had so much fun with. It was a way to thank all of the people who worked on the show over the years that we thought made the show work.

Very early on in my career, I hit upon this idea of being the Heckle Therapist. So that when people would say something nasty, I would immediately become very sympathetic to them and try to help them with their problem and try to work out what was upsetting them, and try to be very understanding with their anger. It opened up this whole fun avenue for me as a comedian, and no one had ever seen that before.

I thought "This is the pinnacle of life, to me: if [I] could do this-- y'know, if [I] could stand up on stage and make people laugh, that would be the ultimate accomplishment of my personality!" And I just thought "Laughs! To be working with laughs and jokes all the time: what a fun life that would be!"
