I was born in 1967, so the 1970s episodes and skits I love the best.
Never seen the shows from the 1980s and the only ones from the 1990s are the ones I see on Noggin (which I do like a lot, except for some annoying characters!!).
And I don't dislike the current version or Play With Me. It's not as bad as I feared. I'd much rather watch those with my kid than Blues Clues or Teletubbies which makes my brain mushy.
