(emerging from bathroom, buttoning his shirt) A gymnast! I can't believe it, you didn't tell me she was a gymnast.

Jerry

(watching George buttoning his shirt) What is this?

George

What, I'm puttin' my shirt back on.

Jerry

(stares at George, incredulous) 'Back on'? What was it doing off?

George

I take it off when I go to the, uh, y'know, to the 'office'.
