A pig wandered into a meadow where a flock of sheep were grazing. The shepherd caught it and was about to take it to the butcher's when the pig began squealing loudly and struggling to escape. The sheep scolded it for making such a fuss, saying, "The shepherd catches and drags us off regularly, and we never make any noise."
"No, I'm sure you don't," replied the pig. "But my situation and yours are completely different. He only wants you for your wool, but he wants me for my bacon."
