Here is the rest of today’s joke.

Mrs. Callahan walked into the grocery store with a paper coupon folded neatly in her purse.
She put a loaf of bread, two cans of soup, and a small bag of apples on the belt. Then she handed the cashier the coupon.
The cashier looked at it, turned it over, and called the manager.
The manager came over and squinted at the date.
“Ma’am,” he said, “this coupon expired in 1987.”
Mrs. Callahan nodded. “I know.”
The manager blinked. “Then why did you bring it in today?”
She tapped the store logo printed across the top.
“Because it says right here, “Good for loyal customers,”” she said. “And young man, I’ve been waiting nearly forty years to see if you meant it.”
Did that one get you?
