Tit For Tat
The prize bull-dog attacked a farmer, who defended himself with a
pitchfork, and in doing so killed the dog. The owner was greatly
distressed, and reproached the farmer.
"Why didn't you use the other end of the fork," he demanded, "and just
beat him off, without killing him?"
"I would have," the farmer answered, "if he had come at me with the
other end."
