Four astronauts land on the moon. An American, a German and two Serbs.

The American jumps out and plants a flag on the surface exclaiming that US derring-do and money made their mission possible so the moon will belong to America.

The German pulled out the flag and stuck in a flag from his country proclaiming that it was German scientific knowledge and technological precision that made the landing possible, so the moon was Germany’s.

One of the Serbs reached into his pocket and pulled out not a flag but a gun and he shot the other Serb. Then he proclaimed: “Serbian blood has been spilled here, so the moon will be Serbian now forever.”

(explanatory note for Mom: In the
14th century Serbs died in a battle in Kosovo and now Serbs still claim
ownership of that province even though it’s like 98 percent Albanian.)
