The Bizzaro Jerry is such a fantastic episode:
Jerry's house, it's dark, JERRY is sitting at the table waiting up as KRAMER comes in and turns on the light.
KRAMER
Jerry. Hey Jerry?
JERRY
I'm right here. You're late.
KRAMER
Yeah, well, I got held up, you know. What happened to your hand?
JERRY
Like you care.
KRAMER
The work piled up, I lost track of time--
JERRY
Oh! Sure! Sure! You an' your work! Elaine's off in the Bizarro World, George only calls when he wants something, and I'm left sitting here like this plate of cold chicken, which, by the way, [drops chicken into sink] was, for two.
KRAMER
You cooked?
JERRY
I ordered in. It's still effort.
KRAMER
Ow! Jeez!
JERRY
What's wrong?
KRAMER
It's my stomach.
JERRY
You're probably getting an ulcer. This job is killing you! It's killing Us...
KRAMER
You know what? You're right. These reports, they can wait a couple of hours. Whadda say we go out tonight? Any place you want.
JERRY
The coffeeshop?
KRAMER
You got it, buddy.
JERRY
I'll call George!
I just love that dynamic.
Then Krmaer getting fired
KRAMER
What did you want to see me about, Mr. Leland?
LELAND
Kramer, I've.. been reviewing your work...Quite frankly, it stinks.
KRAMER
Well, I ah.. been having trouble at home and uh.. I mean, ah, you know, I'll work harder, nights, weekends, whatever it takes..
LELAND
No, no, I don't think that's going to, do it, uh. These reports you handed in. It's almost as if you have no business training at all...I don't know what this is supposed to be!
KRAMER
Well, I'm uh, just--tryin' to get ahead..
LELAND
Well, I'm sorry. There's just no way that we could keep you on.
KRAMER
I don't even really work here!
LELAND
That's what makes this so difficult.
