Charlie Todd causes bizarre, hilarious, and unexpected public scenes: Seventy synchronized dancers in storefront windows, “ghostbusters” running through the New York Public Library, and the annual no-pants subway ride. At TEDxBloomington he shows how his group, Improv Everywhere, uses these scenes to bring people together. (Recorded at TEDxBloomington, May 2011, in Bloomington, Indiana. Duration: 12:04.)
