Take former bad boy turned doting dad, Johnny Depp, bragging, 'My goal in life is to be, above all else, the best of fathers. I don't want to miss any part of her [his daughter Lily-Rose] growing up.' Or Johnny Vaughan saying, 'I truly believe the three-wheel, all-terrain pushchair has taken over from the sports car as the ultimate male accessory.' Then there's Ozzy Osbourne hamming it for MTV's docusoap The Osbournes, as clueless but lovable Metal Dad - a Homer Simpson with tattoos, if you will - telling his kids, 'I f*****g love you more than life itself.'
