Seinfeld1989

Jerry:
I don't understand. Do you have my reservation?

Rental Car Agent:
We have your reservation, we just ran out of cars.

Jerry:
But the reservation keeps the car here. That's why you have the reservation.

Rental Car Agent:
I think I know why we have reservations.

Jerry:
I don't think you do. You see, you know how to *take* the reservation, you just don't know how to *hold* the reservation. And that's really the most important part of the reservation: the holding. Anybody can just take them.
