Caroll Spinney

When he first started - Jim Henson, who created Bid Bird and Oscar - he said Big Bird was just a big, goofy guy. And it was - a script came along and I said, 'I think Big Bird would be much more useful to the show if he were a child learning all the things we were teaching in the show.' And so he didn't know the alphabet, even, for instance.

Big Bird went through his very human kind of struggles as a child. No other children's character has been that complete and detailed.

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.
