Lance Armstrong stopped by "The Tonight Show" last night to talk about his new book, Comeback 2.0, with Conan O'Brien. The pair discusssed everything from Armstrong's muscular legs to the Whizzinator, a prosthetic penis used to circumvent drug tests.
Armstrong talked about his family, telling O'Brien that his kids are the last in their class to learn how to ride bikes, and jokingly took a couple of shots at Ben Stiller, who has launched StillerStrong, an organization that bears remarkable similarities to Lance Armstrong's charity LiveStrong.
