A Kentucky farmer of advanced years took a lovely young bride. At first
the marriage was very passionate and the couple made love frequently.
One day the wife suddenly became disinterested in sex.  The old farmer
shrugged it off as moodiness but after a few weeks of nearly no sex, he
began to worry.

After another few months had passed, the farmer started suspecting foul
play, that maybe his wife was fooling around.  So one day he left the
tractor running out in the field and crept back to the house where he
caught his wife and her young lover in the act.

While his wife and the young guy were scrambling for their clothes, the
farmer fetched his shotgun and burst into the room.  The understandably
hysterical young man pleaded for his life.  The farmer lowered the barrel
and pointed toward the barn.

The farmer led the man at gunpoint out to the barn where he proceded to
secure the man's "unit" in a bench vise.  The farmer then welded the vise
screw so it could not be loosened.  The farmer pulled out a gleaming
sharp bowie knife.

The man was screaming now and begging the farmer not to cut of his
manhood. The farmer just smiled and handed the man the knife while he
said "Oh, I'm not gonna cut it off.  I'm gonna set the barn on fire."
