"The Babysitters" was recorded on April 6, 1960, and first aired on Nov. 11, 1960.
These are my comments and questions about the episode:
1. The 1960 theme and opening credits are played.
2. I believe this is the first appearance of Fred's friend Joe Rockhead. Joe has a pet runtosaurus that Egbert befriends.
3. Egbert's mother is named Edna Boulder. She is part of Wilma's and Betty's bridge group. Edna will reappear in a later episode.
4. In this episode, Barney works for H. Granite and the Granite Building.
5. This is one of several pre-Pebbles episodes involving Fred haplessly taking care of a baby.
