Cosmo Kramer: These pretzels are making me thirsty!
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.
