Yes, as unlikely as it sounds, I was a guest on Charlie Brooker's Weekly Wipe. They wanted to spoof science documentaries and asked me if I would take part. I was to answer questions from Diane Morgan's brilliant character Philomena Cunk, as she grappled with the mystery of 'What is Time?'

The whole episode will be in iPlayer in the Uk for a week. You can watch that here.
