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.
