The Salesman...
There's this travelling salesman who's covering the country side selling who knows what. Late one evening, as expected, his jalopy breaks down. He's the only one on the road and he's surrounded by barren land as far as his eyes can see. However, he spots a house about 1 mile off the road. He decides to try his luck. So he spends the next half hour reaching this house. Reaches there, and knocks on the door. The obligatory farmer answers the door.
Salesman: "Sir, my car just died on me. Could you put me up for the night. I'm willing to pay."
Farmer : "Yeah, sure. You can share the room with my son."
Salesman: "What is going on!!! I'm in the wrong joke!!!"
