An Apache goes into a bank and asks for a loan of 200 dollars. The bank manager asks for collateral: "I have 150 horses," says the Apache, so the bank manager lends him the money.
A month later, the Apache comes into the bank with 2220 dollars in his hand and pays off his debt with interest. "Wouldn't you prefer to deposit the rest of your money with us?" asks the bank manager.
The Apache looks at him suspiciously, then looks around the bank: "How many horses you got?"
