I was watching TV Guide Channel last night (hey, my Comcast was off, I didn't know what was on, and didn't have anything to watch), and they were interviewing "Game Show Millionares". They were speaking with a Jeopardy millionare, and in addition to learning so much over the years, he said the best part of his life was being on Sesame Street. They then showed a behind-the-scenes footage of Big Bird and that mallard duck that pops up from time to time (recently popped up as "Igor" in A Celebration of Me, Grover". The shot was from outside Big Bird's doors, so I couldn't see clearly who the muppeteer of the duck was. And the close up of him was a back shot, so that didn't help any. Anyone know who this muppeteer was?
