The phone rings at FBI headquarters. "Hello?" "Hello, is that FBI?" "Yes. What do you want?" "I'm calling you to report my neighbor Tom, he is hiding marijuana in his firewood." "This will be noted."

 Next day, the FBI comes over to Tom's house. They search the shed where the firewood is kept, break every piece of wood, find no marijuana, swear at Tom and leave.

The phone rings at Tom's house. "Hey, Tom! Did the FBI come?" "Yeah!" "Did they chop your firewood ?" "Yeah they did." "Okay, now it's your turn to call. I need my garden plowed."
