That makes no sense, I'm sure there are people who would pay to sniff Pit's dirty sock lint. So, I can imagine making his mother a millionare just to write and sign a book about being Brad Pit's mother. Hell, I can imagine suckers paying thousands of dollars just to have a phone conversation with Pit's mother. Pit also is wealthy enough to support his mother 10 times over. The autograph of a senile old coot with personality disorders is pretty much crap compared to all the other options Pit's mother has.
