The God Delusion
Dawkins himself responded to critics of "The God Delusion" who argued that he is not a theologian and stated, "Most of us happily disavow fairies, astrology, and the Flying Spaghetti Monster without first immersing ourselves in books of Pastafarian theology." Dawkins quoted the courtier's reply in a debate with Alister McGrath, and he also referenced it in the preface to "The God Delusion"'s 2007 paperback edition.
