Ok, this one's weird.
There's a farmer who has 3 daughters. He is very overprotective of them and on the night of their first dates he locks them in their rooms and stands by the door with a shotgun. The first date arrives.
"My name is Joe, I'm here to get Flo, we're gonna watch the show, is she ready to go?"
The farmer lets the boy take his daughter on the date. The second date arrives.
"My name is Benny, I'm here to get Betty, we're gonna get some spaghetti, is she ready?"
The farmer says ok and lets them go. The thrid date arrives and says
"I'm Chuck."
The farmer shoots him.
