A condom saleswoman was stranded in the country-side and had to put up the night with a farmer and his two hilly-billy sons.
In the middle of the night, she crept into the room where the two brothers were sleeping and woke them up to have sex. She explained that the condoms were to ensure that she did not get pregnant. The next morning she bade them farewell and left the farm.
Weeks passed and then one brother spoke to the other, "It has been some time now that she's gone and I don't think she'll ever get pregnant. Let's take these darn things off."
:D
