Reminds me of this oldie but goodie: A smart businessman went to a bank near the airport to borrow $10,000 for his overseas trip. The bank demanded collateral, so he left his Rolls Royce in their warehouse vault. A week later, he returned, paid back the $10,000 principal, the $19.23 interest (10% per annum for 1 week), and picked up his car. After he did this several more times, the loan officer asked him, "It's obvious you have plenty of money. Why do you have to borrow every time you travel overseas?" To which the smart businessman replied, "Do you realize how much it would cost to park my Rolls Royce at the airport for a week?"
