Quote from Cliff in Feeble Attraction
Cliff: You know, a postal carrier is pretty much the Indiana Jones of your civil servants. Just as Indy faces off a pit of rattlesnakes or a sewer full of rats, I have to, daily, mind you, trade wits with the Flannigans' dog. Doris: Oh, Cliff, when you get out of the service, could we go out together? Cliff: Well, uh, you know, Doris, there's actually no rule against mailmen dating women. It just sort of turns out that way.
