(Into phone) How do you figure? (To Kramer) 'Cause you're the one who left the door open.
Kramer
Why was I in charge of closing the door?
Jerry
(Into phone) Why was he in charge of closing the door? (Irritated at the phone message relay, to Kramer) 'Cause you came in after him!
Kramer
So!
Jerry
(Into phone) So! (To Kramer - getting even more angry) So, the last person in should close the door!
