Indeed, cute, but it's a problem that kids are such a low priority for Sesame Street. I'm sure it brings in money for PBS. But Fred Rogers never did this kind of thing because kids were his only priority.
To the people who are moaning about it not being targeted for children; I was glued to Sesame Street for years back in the 70's and early 80's and trust me; at least *this* makes sense. Half the stuff back then was acid-tripping disco fodder. You're telling me that the above doesn't teach children the difference between "upside down" and "right-side up"? Find something useful to fuss about and just enjoy how awesome this is.
