Toby Ziegler:
I throw a rubber ball against the window; that means you come to me. As my frustration level grows, so does the velocity of the ball against the window.

Will Bailey:
Don't you ever worry about the window breaking?

Toby Ziegler:
During moments of peak frustration: when the Speaker of the House threatened to repeal the 16th Amendment, a couple of Yankee games, and when Congress censured my boss... but it's always held up, that window; that window is a game-day player.
