The rights of ownership

The big bad wolf was at it again. This time he had crept up on a flock of sheep in the dark and killed one. Now he was carrying it back to his den to enjoy a lazy day. Suddenly a lion leapt into the path before him. The wolf got such a shock his mouth dropped open. The sheep fell out at the lion's feet. "That's very kind of you," said the lion. "This will save me the trouble of going out hunting." "You can't take that," spluttered the big bad wolf.. It belongs to me." The lion looked at him and slowly raised one eyebrow. "Really?" he said. "Did the sheep give you permission to kill it and take it home then?"
