That's cool. I have no idea why but I always pictured the person doing the voice as female.

Oscar was actually played by the same actor!

I've always been fascinated with the Henson Company. Carol Spinney did a fantastic jobas big bird. Noel MacNeal works a similar type of puppet by playing BEAR, in Bear in the big blue house. Very cool.
If I had to do it all over again, I'd more than likely try to work in Henson Studios. Very fascinating. Genius actually.
