Give a man a fish and you feed him for a day. Teach a man to fish and it won't be two weeks until he's banging on your door day and night, trying to trade his fish for your oldest daughter.
"Go sell those fish and bring me $10,000 and we got ourselves a deal."
Of course, he has to eat part of his catch or starve and before a couple months he'll be so sick of fish, he'll go rob a bank or something.
