Quote from Harry in Glengarry Glen Dick
Dick: We simply need to raise another $5,000, and a getaway at Pine Villa Estates will be ours. Harry: Well, I guess it's time we sold that old refrigerator of ours. It is, after all, solid gold. Sally: No, Harry, I think the refrigerator is harvest gold. Harry: There are three grades of gold: fool's gold, black hills gold, and harvest gold being the most valuable. Sally: I did not know that.
