Using his preteen alter ego, "Little Billy," author Bill Geerhart wrote to both the famous (Egg McMuffin lover, Supreme Court Justice Clarence Thomas) and the infamous (convicted murderer Charles Manson) -- and received replies from many of them.

The faux 10-year-old also struck up correspondence with Donald Rumsfeld, Oprah Winfrey and Tori Spelling, who each wrote back, offering such thoughtful advice as "stay in school." The greatest hits have been collected in the new book, "Little Billy's Letters," on sale now.
