How about, it isn't cruel at all? There is nothing about fishing that is cruel. Those fish that Oswald left on the bank did not go to waste.
Where's the beef: How do you feel about cows. Same deal?
Do you tip them over by any chance? That would annoy them I suppose.. plus you could tease them with 'Help. I've fallen and can't get up. Moooo."
Although appearing to be cowed, they asked the pigs (who were more equal than the other animals because they said so) for guidance, who in turn encouraged them to eat more baked beans, try not to tip over, and lift a hind leg to the falling sky. The result made the animals on the farm hee-haw, quack, moo, purr, gobble, bleat, baa, cluck, oink, bark, hoot, neigh, hiss, chirp, and cock-a-doodle-doo their approval of Orwell the Head Pig's advice as the cows farted away the ozone layer.
