Have you read Bret Hart's book? Lot's of "inbreeding" in the wrestling world. Could easily be related. It is a fantastic look-a-like.
If you haven't read Bret's book though, it is brilliant. I've read scores of sporting autobiographies, this is by far the best. You'll laugh and cry. I read it in two sittings.
The worst autobiography, by miles, Diego Maradona. Nothing at all about drugs or Castro or guns.
