The Apartment Season 2, Episode 5

George

She's right above you?

Jerry

Right above me.

George

How could you do that?

Jerry

'Cause I'm an idiot! You may think you're an idiot, but with all due respect, I'm a much bigger idiot than you are.

George

Don't insult me, my friend. Remember who you're talking to. No one's a bigger idiot than me.
