I was asked to be on 'The Colbert Report' last year as Big Bird and Oscar. But when we got there, we discovered they wanted both characters on at the same time. Stephen Colbert didn't know one man plays them both. We called Joey Mazzarino, our head writer, who's a very good puppeteer as well. He agreed to zip over and do Oscar.
