The scene: a bunch of British teenagers at school. The opportunity: to put the questions they really want to ask about sex to a panel of experts. The catch: they don’t know it but the experts are the parents. It’s hard to tell who was more embarrassed.

The kids write down their questions ,which are duly delivered to the parents in a Secret Location. The anxious parents try to swat up sexually transmitted diseases 101 and other things they’d perhaps rather wish their kids were too young to know about. This was amusing, but nothing beat the kids’ faces when the ‘experts’ entered the room. Pink, doubled over, hands in faces, heads shaking: No! How could you do this? The presenter rubbed it in, with salt. She asked ‘Do any of you wish you’d written down different questions now?’

The kids took the golden opportunity to ask their parents embarrassing personal questions. Sweet revenge. Make them expose themselves on national TV. The parents valiantly tried to act all-knowing but they didn’t always pull it off. I bet they’ll blame any nervousness on having the cameras on them. I swear the word ‘awkward’ has never been used more frequently in a single programme. This I know too – as a teenager I’d have walked right out of there.
