Hilary Price's cartoon Rhymes with Orange, 8/20/05. "The Origin of Species": CAT: Beef comes from cows, pork comes from pigs, but chicken comes from... chickens. Isn't that strange? DOG: Not really, considering duck comes from duck and roe comes from rodents. CAT: Roe comes from fish. Dog: Yeah, sure--and ham's not from hamsters.
