How much is it?

Flight Attendant:
It's free.

It's what? Holy shit, this is incredible. Actually, I shouldn't drink. I fell in love with this girl who's going to marry an idiot, so I'm on my way to Vegas to stop them.

Female Passenger:
[overhears] That's the sweetest thing I have ever heard! Where are they getting married?

That's the problem, I don't know where, but I'm going to run around and find them. I got to do what I got to do.
