The phone rings at FBI Headquarters:
"Hello" "I'm calling to report my neighbor, John Smith. He is hiding cocaine inside his firewood."
"Thank you very much for the call, Sir."
Next day, FBI agents descent on Smith's house. They search his shed where he stores his firewood, using axes they bust open every piece of wood and find no cocaine. They swear and leave.
The phone rings at Smith's house:
'Hey, did the FBI come?' 'Yeah'
'Did they chop your firewood?' 'Yep'
'Great, now it's your turn to call, I need my garden plowed!'
