One of my favorite parts about the show is how they can spoof pop culture and/or get interesting celebrities to come and good around on their show, all in the name of children’s education.  A cursory glance at Youtube shows they’ve still got it.

Mad Men spoof – complete with sanitized version of beginning credits (i.e. he slips on a banana peel, doesn’t jump out of a building).

Michelle Obama growing a garden – she sounds a lot like Susan, reminds me of the show as I remember it!

Feist sings 1,2,3,4 on the street – slight changes to the lyrics and it fits right in.
