One bit of dialogue I absolutely love is the dialogue between Sid and Jerry in Season 3's "The Alternate Side" (The one with "These pretzels are making me thirsty!")
Jerry: This Wednesday?
Sid: No, next Wednesday, week after this Wednesday.
Jerry: But the Wednesday two days from now is the next Wednesday.
Sid: If I meant this Wednesday, I would have said this Wednesday. It's the
week after this Wednesday.
I always like to use that dialogue to confuse people to the point where they just don't want to listen anymore... Other people I do it with for fun, but they're fans of the show and they've seen the episode, so they know where I'm going with it.
Anyone else have any other favorite quotes that you tend to use with other people (as part of regular conversation, not disvussing "Seinfeld"...hehe)?
