The early seasons of Sesame Street have the kind of raw feeling where an actor's personal animus about women working could slip through. It's an unpredictability that's kind of fascinating, but as a parent, it's also annoying and unreliable.
Read it all; it gets...odder. But seeing as the Beast and the Noodle have skipped most of Sesame Street and jumped straight into the Muppet Show without much in the way of previous Muppetrination, I can only guess as to what they might think of the Street circa 1969.
