Every New Yorker reader must have met Ruth McKenney and her sister, Eileen, and chuckled and laughed uproariously over their misadventures from infancy on. Unmistakably autobiographic, these stories span the generation to which many of us belong, and are colored by details that are reminiscent. Adventures in growing up -- and they have never been better done. For the essential flavor, try Hun-gah and A Loud Sneer for our Feathered Friends. Then I defy you to stop. There's humor -- and a certain twisted pathos -- and abundant humanity. And it's grand reading. Try it with the family.
