Two of my favourite entertainers – in fact, the world’s favourite entertainers – are the magical and comical duo of Penn and Teller. The American illusionists Penn Jillette and Raymond Teller celebrated 40 years in the business with a five night gig this month at London’s Eventim Apollo.

They have been the resident headliners at the Rio in Las Vegas since 2001, and appear regularly on the small screen, including a show called ‘Bullshit!’. The 2,494th star on the Hollywood Walk of Fame was dedicated to them in April 2013.
