For the past decade, comedian Jon Richardson's life has been driven by a quest for perfection. It has dictated everything from his eating habits and his relationship with his mother, to his ability to go on dates or entertain the idea of living with his friends. People have said he has OCD, but he is not so sure. Here he gains an insight into the world of obsessive compulsive disorders, talking to some of the millions of sufferers in the UK and staff who treat patients with the most extreme form. He also chats to his own family and friends - including fellow comic Russell Howard - about his own condition and meets one of the country's leading experts to find out once and for all whether he is simply a demanding perfectionist or if he has OCD.
