He’s so anxious that it took the presenter 47 years to even try ham. This travelogue, in which Ant and Dec send him to South Korea to overcome phobias – including nudity – is strangely charming

What can I tell you about Stephen Mulhern? He’s an ITV presenter (Dancing on Ice, Deal or No Deal, You Bet), magician, longtime friend of Ant and Dec, he’s never had hummus or tasted a prawn, and he’s only recently been introduced to ham. “I like what I like,” he says simply, when Ant (or Dec – I never did have them straight in my mind and it’s honestly too late to start now) asks him how it is possible to have avoided ham for 47 years.

“He’s odd,” says Dec (maybe – see above) fondly. “He’s an odd man.” “Sheltered,” supplements Ant. “Set in his ways.”
