Place and time: somewhere in the Soviet Union in the 1930s.
The phone rings at KGB headquarters.
"My neighbor Yankel Rabinovitz is an enemy of the State. He is hiding undeclared diamonds in his woodshed."
"This will be noted."
The next day, the KGB goons go over to Rabinovitz's house. They search the shed where the firewood is kept, break every piece of wood, find no diamonds, swear at Rabinovitz, and leave.
The phone rings at Rabinovitz's house.
"Hello, Yankel! Did the KGB come?"
"Did they chop your firewood?"
"Yes, they did."
"Okay, now it's your turn to call. I need my vegetable patch plowed."
