Once upon a time there was a farmer whose wife had died and left him withthree beautiful teenage daughters. Every weekend, when they went out on dates, the farmer would stand at the door with his shotgun, making it clear to their dates he wanted no trouble from them.
One Saturday night, there was a knock on the door. He answered and the young man said,
"Hi, my name's Joe. I'm here for Flo. I'm taking her to the show.Is she ready to go?" The farmer thought he was a clever boy andwished them a good time for the evening.
A few minutes later, another knock was heard. A second boy appeared and said,
"Hi, I'm Eddie. I'm here for Betty. I'm taking her for spaghetti.I hope she's ready." The farmer thought that he must know Joe so he offered them his best wishes as well for a fun and swell evening.
A few minutes after that, a third knock was heard.
"Hi, I'm Chuck..." And the farmer shot him.
