OK, I can sleep at night now!
About ten years ago, before I'd ever watched Seinfeld, a co-worker had a Seinfeld calendar. Each month featured stills from the show and the quotes that went with them.
There was one set of quotes I remembered, but I could never find it in any of the Seinfeld scripts on this site. I began to doubt my memory; maybe I had actually seen it on the person's "Friends" calendar or something?
Well, I was just watching the Notes About Nothing on THE VISA, and I discovered that the quotes I saw printed on the calendar were in fact CUT FROM THE EPISODE! It's the exchange that the N.A.N. say would have followed this part:
Elaine nods her head in approval.
George: You mean that's true, I'm right?!
Glad to discover I'm not crazy. Interesting that they would put unused dialogue on the calendar.
