In my youth the cool hero of choice was The Fonz, played by Henry Winkler in the US TV sitcom Happy Days. He wasn't just cool, he was ice cool. He was the guy who always got the girl, played the hard guy but in reality was an old softie. And Richie Cunningham's mother fancied the pants off him.
So it was with some degree of shock that I turned to page 12 of today's Telegraph to find a picture of him reading a kids' book with Ed Balls. And he looked like the definition of the word 'uncool'. He looked squarer than Richie Cunningham, wearing a David Davis-esque stripey tie.
Somehow I felt old. That part of my childhood died in that picture.
