For a long time I couldn't tell you his name, but I'd try to imitate his slow, monotone voice and contrary take on otherwise common things. (I wasn't ever very good at it.) With time though, his very distinct kind of humor has become better known, and most people actually know exactly that voice, when I ask, "Have you heard of Steven Wright?" ( Edited by karj )
