George: "Are you crazy?!!!!!" (reacting to Jerry saying he's not going to do the menage. His physical acting is great.) (from "The Switch")
Jerry: "No, all new material! He's never seen it! I did it at the (something) last week. It killed!" (convincing a friend that he should have another chance to make Fulton laugh. "It killed" is foreshadowing, as the material would later "kill" Fulton) (from "The Stand-In")
Frank: "It's kinda unnatural but I think I'm gettin' the hang of it." (while Kramer embraces him from behind, showing him how to stroke the cue) (from "The Doll")
George's potential employer: "It's quieter here. We can talk, without a lot of people whooshing around." (then George's pants whoosh and everyone freezes) (from "The Pie")
Jerry: (his wordless but hilarious reactions to Ms. Chang saying "ridicurous") ("The Chinese Woman")
George: "The rines are crossed?" (confused by Jerry's statement that was a jab at Ms. Chang) ("The Chinese Woman")
Poppie: "It's a pizza as soon as you pudda your fists in the dough!" (arguing with Kramer over what is and is not a pizza. Parallels the abortion issue: what is and is not a human life.) (can't recall episode title)
Jackie Chiles: "You people with the cheese! It never ends!" (Complaining to a restaurant delivery boy about his sandwich) (from the Final Episode?)
The Bizarro George: (the fact that he stands up politely when Elaine walks into Kevin's apartment. The opposite of George) (From "The Bizarro Jerry")
Mickey: "That little bastard!" (referring to another "little person") ("The Stand-In")
George: "The door?" (when George's girlfriend asked him why he didn't leave through the door, instead of the window. He acts like she has suggested the strangest thing in the world.) (From "The Cafe")
That's all for now.
