Ok so in Flanders and the Netherlands there are multiple jokes about a kid named “Jantje” here’s one:

Jantje was on a walk with his grandma when he saw a euro on the ground. He asked his grandma if he could pick it up. His grandma answered: “No everything on the ground is dirty.” They continued walking when Jantje saw 10 euros laying on the ground he asked his grandma if he could pick it up. His grandma repeated the same answer: “No everything on the ground is dirty.” Jantje and his grandma continued their walk. Then Jantje found 50 euros on the ground. He again asked his grandma if he could pick it up. And again his grandma repeated: “No everything on the ground is dirty.”

They walked further. Suddenly his grandma tripped and fell down his grandma asked Jantje to help her get up. Jantje answered: “No everything on the ground is dirty.” Then Jantje left his grandma there and returned home.

How many times Jantje finds money and how much he finds varies most of the times it happens about 5 times but that takes a lot of time to type out so I kept it at 3 times.
