Season 4, Episode 5: "The Wallet"

What happened to you?

Oh, some guy kicked me in the side of the head.

-What guy? -Crazy Joe Davola.

-Why? -Well, I was having this party...

...and I didn't invite him, and then Jerry tipped him off.

Why did you tell this guy that Kramer didn't invite him to his party?

I didn't know he wasn't invited.

Hey, these are very comfortable pants.
