The phone rings at KGB headquarters.
 
  "Hello?"
  "Hello, is this KGB?"
  "Yes. What do you want?"
  "I'm calling to report my neighbor Yankel Rabinovitz as an
  enemy of the State. He is hiding undeclared diamonds in his firewood."
  "This will be noted."
 
  Next day, the KGB goons come over to Rabinovitz's house. They
  search the shed where the firewood is kept, break every piece
 of firewood but find nothing.
  The phone rings at Rabinovitz's house.
 
  "Hello, Yankel! Did the KGB come?"
  "Yes."
  "Did they chop up your firewood?"
  "Yes, they did."
  "Okay, now it's your turn to call. I need my vegetable patch plowed."
