What's your favorite Seinfeld line?

Newman: Colombia?! What kind of snow blower did you get us mixed up with

 

Jerry talking to a priest about his dentist: I think he converted to Judaism just for the jokes.
Priest: And this offends you as a Jewish person.
Jerry: No, it offends me as a comedian

 

one more before I fall asleep

George (talking about peeing in the shower): It's not good to hold it in. I read that in a medical journal.

Jerry: Did your medical journal mention anything about standing in a pool of somebody else's urine?

 

I love any quote dealing with George and bathrooms or peeing.

 

They do have their own schools!

 

"She's got the man hands!"

"He's a close talker."

"She's a low talker"

 

Same episode, I love the scene when Kramer goes to the guys house to get the statue back.
A few highlights:
"Are you a cop" "Yeah, I'm a cop, I'm a damn good cop"
and "Make love to the wall you pervert"

 

Maybe a dingo ate your baby.

 

Any scene with David Puddy is gold!

"Yeah, that's right."

Elaine: So how long have you been a Devils' fan?
Puddy (off camera): Since I was a kid, I'm from Jersey.
Elaine: Yeah? Well, we're gonna kick your butts tonight.
Puddy: Hey, no way, man.
Elaine: Yes.
Puddy: We're primed.
Elaine: Alright, you almost ready? Cause Jerry and Kramer are gonna be here
any second.
Puddy enters wearing a Devils' jersey and red and green paint all over his face.
Elaine: What the--
Puddy: So what do you think?
Elaine: What is that?
Puddy: I painted my face.
Elaine (still in disbelief): You painted your face?
Puddy: Yeah.
Elaine: Why?
Puddy: You know, support the team.
Elaine: Well, you can't walk around like that.
Puddy: Why not?
Elaine: Because it's insane?
Puddy: Hey, you gotta let them know you're out there, this is the playoffs.
There's a knock at the door, Puddy answers it. It's Jerry and Kramer. Kramer
enters first and does a typical 'Kramer take' when he sees Puddy's painted face.
He recovers quickly.
Kramer: Hey.
Puddy: Hey.
Elaine: Dave, um, painted his face.
Kramer: Yeah, that's cool. Well, you gotta support your team.
Puddy: Ok, ready to go?
Kramer: Yeah.
Puddy (startlingly loud): LET'S GET IT ON!!! Alright!! Go Devils!! Go
Devils!! Let's go Devils!!

 

GEORGE: So that old woman; she was a liar, right?
JERRY: And a bit of a tramp, if you ask me.

I'm not driving him to the airport. (Repeated three times)

And ... as somebody else reported ... And you want to be my latex salesman.
