The Letter (Seinfeld)

[1] Kramer poses for a portrait to be painted by Jerry's new girlfriend, Nina (Catherine Keener), which an elderly, art-loving couple (Elliott Reid and Justine Johnston) admire.

Kramer, while attempting to climb over the dugout to retrieve George's Yankee cap after Elaine threw it, is struck in the head by a baseball.

Upon returning to Jerry's apartment, Elaine discovers her confrontation in the Yankees' owners box was published with a picture in the sports section of the paper.

He informs her that Nina's father has given him tickets to Yankee Stadium and invites her to wear a Baltimore cap (which she coincidentally has in her office) as a joke.

In the closing scene, Jerry and George watch the televised Yankees game, only to find Elaine in yet another cap altercation as described by Phil Rizzuto and Kramer dines with the elderly couple who purchased his portrait.
