You must have never seen Harold & Kumar Escape from Guantanamo Bay
Never made it to my 'Must See' list. Is it an autobiographical movie, or some writer's fantasy?
Actually, I looked it up, so I know exactly what it is. [Ain't the internet wonderful!?] And it proves my point. A writer can create any story he or she cares to devise.
I did see Deliverance, which also proves my point. A different writer's fantasy.
Everyone knows that the incidence of abnormalities increases with inbred children. Hence the higher incidence of hemophilia in some of the European royal families. And yet not all of Queen Victoria's and her cousin's (Prince Albert) descendants were afflicted with that disorder.
PS. I won't mind terribly if this post is deleted as being off-topic.
