Actually, the first two series are generally not that great and it gets much better as it goes along. Probably peaks in the eighth series, which is the one with the English Patient, but there are some great episodes in the final series too (The Merv Griffin Show and The Strike come to mind) and it has a proper ending. Apparently, NBC offered Jerry Seinfeld $110 million to do another series but he turned it down.
I had crab bisque for lunch today, which reminded of a line from another episode from the eighth series (The Yada Yada)...
"Listen to this. Marcy comes over and she tells me that her ex-boyfriend was over late last night and 'yada yada yada I'm really tired today.' You don't think she'd yada yada sex?"
"I've yada yada'd sex."
"Really?"
"Yeah. I met this lawyer, we went out to dinner, I had the lobster bisque, we went back to my place, yada yada yada, I never heard from him again."
"But you yada yada'd over the best part."
"No, I mentioned the bisque."
