Fury's dad: 'Anyone who believes what Tyson says is crazier than me'

John Fury, father of the WBC world heavyweight champion TIson Fury, said his son could not be taken seriously.

“Anyone who believes what Tyson says is crazier than me. It changes with the weather. He may not be interested in something at 10 am, but at 11 am he is already interested. So how can he be taken seriously? Tyson is a fighter, and if it makes business sense, he's willing to do anything."
