Despite the lengths we went to creating a creature no-one would ever want to appear in their lives, we did somehow manage to make one that people loved. A cottage industry sprang up on eBay with homemade versions of Nagging Doubt selling at upwards of £60. I’ve no idea why anybody in their right mind would want to buy these? I have 3, including a Mrs Nagging Doubt and Baby Nagging Doubt, characters we’d not even come up. People were even finding and ringing up the agency to let us know their dogs, cats, guinea pigs looked like Nagging Doubt, a great story for PR and social.
