On Perspective, by John Keating
[Keating stands on his desk]
John Keating: Why do I stand up here? Anybody?
Dalton: To feel taller!
John Keating: No!
[Dings a bell with his foot]
John Keating: Thank you for playing Mr. Dalton. I stand upon my desk to remind myself that we must constantly look at things in a different way.
