A frantic-looking woman came rushing out of her house

A frantic-looking woman came rushing out of her house into the street and cried for help, saying,

“My little son has swallowed a coin and is choking to death.”

Everyone looked the other way, except for a middle-aged gentleman who rushed into the woman’s house, found her little son, turned him upside down and shook him until the coin fell out of his mouth. “Oh, thank you,” cried the woman.

“Are you a doctor? “No,” replied the man.

“I’m from the Income-Tax Department”.
