A decade or so ago, an unemployed 30-something screenwriter named Bill Geerhart thought he'd have some fun by posing as a 10-year-old named Billy who had lots of questions he wanted to ask of famous and infamous people, from serial killers to celebrity lawyers. He actually got replies to his letters, which he collected and just now published as a book called Little Billy's Letters: An Incorrigible Inner Child's Correspondence with the Famous, Infamous, and Just Plain Bewildered.
BoingBoing got permission to run some of them, and they are just priceless. My favorites are from the National Hobo Association and the CEO of Caesars Palace, who basically says gambling is a losing proposition, if fun to do.
Thanks to the incomparable Patti Digh at 37 Days for the pointer.
