This is an interesting piece of history.
During the early days of Sesame Street, it seemed like there was several moments where they didn't mind showing the " Anything Muppet " process.
But what makes this even more interesting is it's literally a blooper reel kept on the show. :)
Remembering Bob McGrath ( & Jim Henson ).
