| The son of a financier bursts into his father's office and says, "Dad, lend me $5,000." "What for?" his father asks. "I've got a sure tip on the market." "How much could we make?" his father asks. "I'd say at least $2,000 - that's $1,000 for each of us." "OK, son. Here's $1,000," his father said. "Let's consider that we have made the deal and it has succeeded. You make $1,000 and I save $4,000." |
