(Moving out into the living room) Jerry, why don't you do a bit on Styrofoam?

Jerry

Like what?

Kramer

Well, uh.. (Starts to impersonate Jerry's act) 'What is this stuff? Why do we need this stuff?.. And why do they make it so small..?'

Jerry

(Confused) Where's the punchline?

Kramer

It's all attitude.. (Makes a humorous face - mocking Jerry's)
