I'm sorry but I don't know the episode titles. I'll edit my post later.
Newman to Jerry: "Alright. You go ahead! You keep it secret but remember this: When you control the mail, you control...in-fah-mation!!"
Newman: "I want the new millenium to be...Jerry-free!!!"
Mr. Bookman's entire speech to Jerry about his overdue library books, especially, "Yeah, you and your good-time buddies!"
Kramer to George (who is eating pretzels and has unknowingly purchased ladies' glasses): "May I have one of those, madam?"
The Mohel to Elaine (after she places a glass on the edge of a coffee table): "You see where that glass is? Why you chose the absolute edge, so have the glass is hanging off the table like that? You breathe and that glass falls over. Then you have broken glass everywhere! Embedded in the carpet fibers, deep in the shag. Broken glass, bits of broken glass, and you can't get it out! You can't get it out with a vacuum cleaner! Even on your hands and knees with a magnifying glass, you'll never get all the pieces! Then you think you got it all. Then, two years later, you're walking around barefoot, you step on a piece of broken glass, and you KILL YOURSELF!! Is that what you want?! I don't think that's what you want?! Is it!? Do ya'?! Huh?!"
Elaine's shrink, Dr. Reston (into the phone): "Yes, Bobo?" I have no idea why I laugh at this.

Kramer (who had been swimming laps in the YMCA pool until the senior citizens came in): "It was like a flabby-armed spanking machine!"
