Finders Keepers

[Rondy]

An elderly couple who were childhood sweethearts had married and settled down in their old neighbourhood and are celebrating their fiftieth wedding anniversary. They walk down the street to their old school. There, they hold hands as they find the old desk they'd shared and where he had carved "I love you, Sally."
On their way back home, a bag of money falls out of an armoured car practically at their feet. She quickly picks it up, but they don't know what to do with it so they take it home. There, she counts the money, and it's fifty-thousand pounds.
The husband says, "We've got to give it back."
She says, "Finders keepers." And she puts the money back in the bag and hides it up in their attic.
The next day, two detectives are going door-to-door in the neighbourhood looking for the money and show up at their home.
They say, "Pardon me, but did either of you find any money that fell out of an armoured car yesterday?"
She says, "No."
The husband says, "She's lying. She hid it up in the attic."
She says, "Don't believe him, he's getting senile."
But the agents sit the man down and begin to question him. One says, "Tell us the story from the beginning."
The old man says, "Well, when Sally and I were walking home from school yesterday..."
The detective looks at his partner and says, "It's time to go...Let's get out of here."
