The Wisdom of Big Bird (and the Dark Genius of Oscar the Grouch) was published in 2003. Although the work's secondary title is "Lessons from a Life in Feathers," the book is partly an autobiography that begins shortly before Caroll Spinney joined the fledgling cast of Sesame Street Muppeteers. Interspersed with Spinney's remembrances are lessons that he learned from playing Big Bird and, to a lesser extent, Oscar the Grouch. In addition to the hardback edition, a large-print version was released on October 1, 2003.
