"Hello, is this the FBI?"

"Yes. What can we do for you?"

"I'm calling to report about my neighbor Billy Bob Smith on Hwy#1...
he is hiding marijuana inside his firewood."

"Well, we thank you very much for the tip-off 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 every piece of wood, but find no marijuana.

They swore at Billy Bob and left shaking their heads.

The phone rings at Billy Bob's house.

"Hey, Billy Bob! Did the FBI come?"

"Yeah!"

"Did they chop your firewood?"

"Yep."

"Happy Birthday Buddy!"
