“‘Dad,’ said Jack one day. ‘When you’re on the telly, d’you think people are laughing with you or at you?’The question had obviously been bothering him for a while.‘Y’know what,’ I said to him, ‘as long as they’re laughing, I don’t care.’‘But why, Dad? Why would you want to be a clown?’‘Because I’ve always been able to laugh at myself, Jack. Humour has kept me alive over all these years.’And it’s true, y’know.”
