Season 7, Episode 12: "The Caddy"

Mr. Steinbrenner, you know, we've searched everywhere.

There's no sign of him.

Not even anyone who remotely fits his description, sir.

-Do you know what this means? -What, sir?

He's dead. Costanza's dead.

-No, no, sir. You see-- -As quickly as he came, he's gone.

The poor little guy.

Easy, Big Stein, get it together.
