One of his latest "flashmob" events was with real quadruplets in Central Park.
Todd is the founder of Improv Everywhere, a New York collective that brings the strange and absurd to public places. The group has undertaken more than 100 missions since 2011, involving tens of thousands of 'undercover' agents. From a fake U2 concert and no-pants subway rides to a book-signing event by a dead author – the group’s surreal performances cause all sorts of confusion and lots of laughter. I note his YouTube channel has over a million subscribers.
Apart from being the driving force behind Improv Everywhere, Todd also performs with the Upright Citizens Brigade Theatre in New York. His book 'Causing a Scene' gives a hilarious insider account of the jokes Todd and his group have pulled over the years. His motto: "You don’t need permission to be creative." My favourite is still the stunt their did with frozen statues in Grand Central Station.
