A group of wealthy gentlemen were sitting at a luncheon arguing over who made the most money...
Man #1 says "I am the wealthiest man here. I am a banker. Every month, I make a handsome profit in the interests on all my loans at once."
Man #2 says "Ah, but I own the operations of a massive oil production. I never even have to work and every quarter my profits triple because demand is so great."
Man #3 laughs and says "I am clearly the richest person here. I own the pieces of land you both use to run your businesses. I own the most important real estate in cities across the country."
Finally they looked upon the last man who they hadn't recognized. One of the men asked "My good sir, what do you do? Are you richer than any of us?"
The man reached into his wallet and took out small pictures and handed them to each of the other men. They began to shuffle uncomfortably.
"But sir," one of them began to say, "Why do you have pictures of our wives in your possession?"
The 4th man replied "I run an alimony enterprise, and those women are some of my best workers."
