You're probably thinking .. who's he? He was the 'warm-up act' last night for Tim Vine at Bolton's Albert Hall last night. Initially I thought the same, then, when he mentioned Penn & Teller I remembered I'd seen him before. As well as other gags & tricks he did the same routine he'd done on the telly. The idea of the tv programme was that if the artist could fool Penn & Teller the prize was a tricp to Vega to be their warm up act.
Needless to say he kept the money again! Same envelope too!
