In the market with his dad, a little boy was flipping a quarter into the air and then catching it with his teeth. Someone bumped the little boy at the wrong moment and the quarter came down and lodged into the boy's throat.
The boy starts to choke and his father starts hollering for help. A middle aged man hears the commotion, casually puts his cart to the side, straightens his coat and tie, and makes his way to the boy and his father.
"Excuse me, sir," the man tells the father. The man reaches down to the still standing (but still choking) boy, carefully takes hold of the kid's balls, and squeezes gently but firmly. After a few seconds, the boy convulses violently and coughs up the quarter, which the man catches in his free hand. The man releases the boy and walks back over to his cart.
After making sure his son is ok, the father walks over to the man and thanks him profusely for saving his son's life.
"I've never seen anyone do that -- that's amazing! Are you a surgeon?"
"Oh good heavens, no," replied the slightly embarrassed man. "I work for the IRS."
