Why should you get the first class?

Elaine, have you ever flown first class?

-No. -All right, then.

You won't know what you're missing.

I've flown first class, Elaine. I can't go back to coach.

-I can't. I won't. -You flew here coach.

-Yeah, that's a point. -All right, fine. I don't care.

The plane crashes, everybody in first class is gonna die anyway.
