A carload of hunters, looking for a place to hunt, pulled into a farmers yard. The driver went up to the farmhouse to ask permission to hunt. The old farmer said, "Sure you can hunt, but would you do me a favor? That old mule standing over there is 20 years old and sick with cancer, but I don't have the heart to kill her. Would you do it for me?"
The hunter said, "Sure," and headed for the car.
While walking back, however, he decided to pull a trick on his hunting buddies. He got into the car and when they asked if the farmer had said OK, he said "No, we can't hunt here, but I'm going to teach that old cuss a lesson." With that, he rolled down his window, stuck his gun out and blasted the mule.
As he exclaimed, "There, that will teach him!" a second shot rang out from the passenger side. And, one of his hunting buddies shouted, "I got the cow!"
