A father has three daughters of dating age

One Saturday night, he hears a knock on the door. He answers to see a young man, who says, "Hi I'm Eddie. I'm here for Betty. We're going out for spaghetti. Is she ready?"

The father nods and calls her down. After a while he hears another knock on the door. The young man says, "Hi I'm Joe. I'm here for Flo. We're going to the show. Is she ready to go?"

The father nods and calls his daughter. After a while he hears another knock on the door. The young man says, "Hi I'm Chuck…"

The father punches him in the face.
