Radcliffe saw the blue box from Doctor Who and asked what it was. I explained that Doctor Who was a show on television about time travel.

His response: ‘I don’t understand. They travel through time in a port-a-pottie?’

When I explained that it was not, he argued that ‘yes, it is a toilet and that is nasty. No, I do NOT want to watch that show with daddy.’

At the end of the conversation, he was clearly exasperated and declared, ‘I’m so stressed I’m losing my Radcliffe muscle!’
