I finished reading this book not but half an hour ago, and it's one of the most amazing things i've ever read. Pinkwater at his very best, but a great deal more than that -- invites favorable comparison the the works of Saki and the early Vonnegut. A witty, astute, hedonistic critique of American culture and education. Buy it right now.
