From Radar Magazine. Basically, a writer posed as a child and sent letters to various people of various levels of fame asking for advice. In one series of letters, little Billy asked serial killers such as Charles Manson and Ted Kaczynski whether he should drop out of school. Most responded.
The article reprints those letters from around 1999 as well as Billy's follow up letters from around 2007.
Also featured is sage advice from other non-serial killers such as Larry Flynt, Allan Greenspan and the Governator.
