Amish Joshua was driving his horse and buggy, on his way to market, when he was pulled over by a State Trooper. The Trooper pointed to the rear of the buggy and stated it was missing the required reflective placard, and told Joshua he would be getting a citation for not having one.
While writing up the ticket, a horse fly kept buzzing around the Trooper's head. The Trooper shouted, "Damn horse fly!!"
"Oh no, Trooper, that's no horsefly, that's a CIRCLE fly." said Joshua.
"A circle fly.....what's that?" asked the Trooper.
"A circle fly circles around a horse's ass on a hot summer day." claimed Joshua.
"ARE YOU CALLING ME A HORSE'S ASS!?!" yelled the Trooper.
"Oh no Officer....." said Joshua, "But you can't fool them circle flies.....!!"
