In a new book called "Little Billy's Letters," Bill Geerhart poses as a little damn kid to write prank letters to famous people and institutions, for kicks. And whattaya know: one of his targets was the Church of Scientology.

Billy writes to the Rev. Heber Jensch.

The Rev. Jensch replies. Tell your friend Eddie we're a church, not a company!

Billy writes in search of knowledge about Thetans, volcanoes, whatever Scientologists are talking about.

Billy receives a wealth of information. Including a donation form. Scientologists: responsive to customers!
