This one comes compliments of Jan:


Phone rings at FBI headquarters. 
"Hello, thank you for calling the FBI hotline."
"Hello Mr. FBI, I'm calling to report my neighbor, Billy Bob Smith. He's hiding marijuana 
inside his firewood."
"Thank you for the tip, sir. We'll get right on it."

The next day, a team of FBI agents descend on Billy Bob's house. They search the shed 
where the firewood is kept. Using axes, they bust open every piece of wood in the shed, 
but find no marijuana. 
They swear violently at Billy Bob and leave. 

20 minutes later, the phone rings at Billy Bob's house.

"Hey, Billy Bob! 
"Did the FBI come?"
"Did they chop your firewood?"
"Happy birthday, buddy!"
