A man walks up to a farmer's house and knocks on the door. When a woman opens the door, the man asks her if she knows how to have sex. Not amused, she slams the door in his face. The man knocks again and again asks the same question.
Again, not amused , the woman screamed to get the hell away. Later, she told her husband of the incident. The husband said he would stay home the following day just in case.
Sure enough, the next day the same man returned. The husband hid with his gun while the lady answered the door. When she was asked again if she knew how to have sex, she said, "Yes."
The man then said, "Great! Give some to your husband the next time you see him and tell him to keep away from my wife!"
