OTTAWA—I once fed a sucker to a gorilla. It sounds bizarre in the telling, but it is true. The gorilla resided in New York’s Central Park Zoo, and my family was in visiting an uncle who lived there in the late fifties. We had just purchased very large, swirled lollipops and were strolling through the zoo when we spied the gorilla. He was housed in a cage with bars wide enough for a child’s arm to gain access.
