Quote from Cliff in Someone Single, Someone Blue
Norm: Tell me, how come you never got married? Cliff: Well, Norm, Coach, it's unfair to ask a woman to be the wife of a mailman. You know, watching him get up every morning, strapping on that old mailbag, going out and hitting those mean streets, never knowing whether he's coming back or not. Norm: Pfft. You're right. Somewhere out there is a beagle with your name on it, right?
