An insect repellent salesman tried to sell his product to a farmer.  He
said he wasn't interested because he hadn't seen any bugs or insects on
his farm for years.  The salesman indicated he had a wife and four kids
and really needed the money.  The farmer still didn't think he needed
any insect repellent but he felt sorry for the salesman and said, "I'm
so sure there aren't any insects around here, if you'll strip naked,
I'll tie you to my barnyard fence for the entire night.  When morning
comes, if you've got even one insect bite on you, I'll buy every can of
repellent you've got."
The salesman was elated and readily agreed to being tied up naked.
That night, the farmer tied the naked salesman to the barnyard fence
and went to bed.  Several times during the night he thought he heard
the salesman moaning and groaning. However, when he went out the next
morning, the salesman didn't have even one bite or scratch on him.  The
farmer asked, "What was all that moaning and groaning about last
night?"  "That was the worst night of my life," the salesman replied,
"doesn't that damn calf have a mother?"   Lyle's Joke Boutique.
