I'm from the same era as Teddy, & I well remember "Romper Room", but apparently it was something like a franchise operation, with each local market doing its own version of the show with their own "teacher"...I remember Miss Eleanor being replaced by Miss Nancy, & unlike Teddy, I was not bothered that they never called my name out as a "do-bee"...I was grateful that they never called me out as being a "don't-bee"...I remember one of the big taboos as standing up while riding in the car, that was the era when a child car seat was considered a luxury for babies to sit in, & it was just a primative device that loosely hooked over the seat back...
The other kiddie show I remember was, of course, Bob Keeshan as Capt. Kangaroo, with Mr Moose, Grandfather Clock, Bun Rabbit, Dancing Bear, & not to forget, that dopey old Mr Greenjeans...we also had a local version of Bozo the Clown, that I actually got to be in the gallery once; the guy that that dressed up as Bozo was actually a deacon in our church...
Mentioning Kermit's 50th reminds me that the Muppets did not start out as a kiddie show thing, I remember seeing the early Kermit on programs such as "The Jack Paar Show", he would hum "Little Glow Worm" & eat every little worm that came along, until a big fat juicy worm comes along, too large for him to swallow in one gulp, he pulls on it & discovers it is the trunk of a huge scary monster thing that devours Kermit instead...not exactly the kinda thing sweet dreams are made of, but I found it fairly amusing as a 6-year-old...
