Quote from Jim in the episode An Old Mustang
Georgie: [on the phone] Yeah, a water pump for the '66 Mustang. You got one? Great. I want it. Well, how much is he paying? I'll pay 20 more. I can hold. [meanwhile, in Jim's office:] Jim: [answers phone] McAllister's. What? We had a deal. 20 more? Trying to jack up the price. Yes, I still want it. Georgie: Oh, really? Well, I'll go another 20. Jim: All right, enough nickel-and-diming. 50 more and that's my final offer. Georgie: What kind of idiot's gonna pay that much for an old water pump? Fine, let him have it. [hangs up] Sucker. Jim: [opens door] Georgie, great news. I got the water pump. Georgie: Sweet. I almost had one, but the guy tried to rip me off. Jim: Joke's on him. Georgie: You're darn right.
