Just one story to back this claim :)
"Hello, is this the FBI?"
"Yes, how can we help you sir?"
"I'm calling to report my neighbor Billy Bob Smith! He is hiding marijuana inside his firewood."
"Thank you very much for the call, Sir."
The next day, the FBI agents descend on Billy Bob's house. They search the shed where the firewood is kept. Using axes, they bust open everypiece of wood, but cant find any marijuana. They swore at Billy Bob and left.
The phone rings at Billy Bob's house. Hey, Billy Bob! Did the FBI come?" said his best friend
"Yeah!"
"Did they chop your firewood?" his best friend asked "Yep." "Happy Birthday, buddy!" his best friend replied.
