An old farmer got pulled over by a state trooper for driving to slow on the
highway. While the trooper was writing him a ticket a big fly kept buzzing
around the cop's face, anoying the daylights out of him. The farmer said "you
know what kind of fly that is officer?" The trooper replied "No, What kind of
damn fly is it ?" The farmer replied back "It's just a big old horse fly,
they're easy to tell them apart cause they're always flying around the ..um
..tail end of a horse" The Trooper was instantly enraged and said "Are you
calling me a horses ass?" The farmer calmly replied back "No sir I sure aint,
but it is mighty hard to fool them flies!"
