An old farmer was hauling a load of manure when he was stopped by a state trooper.

“You were speeding and I’m going to have to give you a ticket.”

“Yep” says the farmer as he watches the trooper shoo away several flies. “Watch out for them Circle Flies!”

The trooper shot back,”What’s a circle fly?”.

“Flies that circle roun’ a horse’s behind.”, smiled the farmer.

The trooper smiles back, “Now you wouldn’t be calling me a horse’s ass, would you?”

“Nope… I wouldn’t do that” the farmer says. “I have too much respect for law.”

The trooper says, “Well that’s a good thing,” and goes back to writing the ticket.

After a long pause, the farmer says, “Hard to fool them flies though.”
