A farmer has three daughters who all have dates tonight.
The doorbell rings and the farmer answers it, the boy says,"Hello I'm Joe, I'm here for Flo, we are going to the show, is she ready to go?" so she comes down and leaves with Joe.
The doorbell rings again and the boy says,"Hello I'm Eddy, I'm here for Betty, we're going to eat spaghetti, is she ready?" and so they leave together.
The doorbell rings a third time and the boy says,"Hello my name is Chuck..." The farmer shot him!
