A farmer is concerned that all 3 of his daughters are going on a date tonight. He decided he'll greet each man who shows up tonight with his shotgun in hand.
The first man to ring the doorbell greets the farmer with, "Hi, my names Joe. I'm here for Flo. We're going to see the show. Is she ready to go?"
The farmer likes this fellow and sends Joe and Flo off.
The second man to show up says, "Hello, I'm Eddy. I'm looking for Betty. We're gonna go eat some spaghetti. Is she ready?"
The farmer decides this guys okay too so off they go.
The third man rings the doorbell says, "Hey, my name's Chuck."
And the farmer shot him.
It's unclear why he decided to do this, as the poor man's name in reality had no bearing on what he was about to say next. More than anything else, it's important to view the farmer's reaction as a chilling commentary on gun culture.
