ARE you a thief? That's the question posed by James Freedman, the self confessed Honest Pickpocket.
He suggests that most of us are - from nicking a few sweets as a kid to taking momentos from a hotel room to even claiming more in expenses than you should.
He also likes to distinguish a thief from a thug - someone who uses violence to steal.
He does all this in a brilliant 80 minute show, Man Of Steal, now on at the Menier Chocolate Factory.
And if you've got any sense, I would urge you to see it - it's quite astonishing.
For not only is it hugely entertaining and at times very funny, it is also incredibly insightful and most importantly education. In fact I would go as far as to suggest it's essential viewing.
It is for everyone - and not just those who've had the misfortune to have their pockets picked.
Through stories, demos, audience participation and chat, Mr Freedman, widely acknowledged as one of the world's greatest pickpocket entertainers, takes us through various scenarios.
He also shows how the minds of the thieves work - and how to be more vigilant to scams and be more aware of our personal safety to stop becoming a victim. He shows us how frighteningly easy it is to become a victim of theft.
Funny and fast fingered he exposes how the bad guys work, done through a life time spent studying thieves of all sorts, from street criminals to hustlers and to conmen.
It is no surprise that over the years he has been an invaluable support to the police and other security professionals.
I'm not going to give anything away - it really has to be seen to be believed - but safe to say the last 10 minutes of the show were more than just eye-opening.
I am sure there was not one person in the audience who did not sit up, take note and gasp at what he showed us.
Man Of Steal takes place at the Menier Chocolate Factory, Southwark Street until April 27. Tickets from £22.50. Visit www.menierchocolatefactory.com or call the box office on 020 7378 1713.
