A Romanian, a Jew and a Somali are all sitting underneath a tree. A caterpillar falls onto the Romanian’s shoulder.
The Romanian flicks the caterpillar at the Jew, the Jew flicks the caterpillar at the Somali, and the Somali picks up the caterpillar and enthusiastically eats it.
A little while later, another caterpillar falls onto the Romanian.
The Romanian flicks it at the Jew. The Jew picks it up with two fingers, turns to the Somali and asks, “Do you want to buy a caterpillar?”
