Captain Kangaroo was a children's television series which, in one form or another, ran from 1955 until 1984 on CBS and was later re-run on PBS. Created by and starring Bob Keeshan, the series combined comedy skits with nature lessons, story reading, animated segments, and puppet characters.
Though the series was not designed to follow a specific educational curriculum, elements of the Captain Kangaroo format influenced the development of Sesame Street. This was in no small part due to the fact that many of the key members of the Children's Television Workshop, including Dave Connell and Jon Stone, had previously worked on the series. Episodes of Captain Kangaroo were studied to test children's attention spans and to help develop the CTW model. 
When scheduling the first season of Sesame Street, Joan Ganz Cooney and associates deliberately avoided the 8 a.m. timeslot occupied on CBS by Captain Kangaroo, so as not to be in direct competition with what CTW viewed as the only worthwhile network children's show. 
- In the 1980s, Matt Robinson was a staff writer for Captain Kangaroo and reused his script for a Roosevelt Franklin skit, specifically the story of Morty Moot Mope. This time, with a more traditional medieval fairytale setting, Mr. Greenjeans (Lumpy Brannum) plays King Morty Moot Mope, while Dennis (Cosmo Allegretti) is Same Sound Brown (more Pied Piper than hipster in appearance). Captain Kangaroo himself plays the storyteller. Outside of an altered ending and the omission of the spanking motif (replaced by putting in a cage in the zoo), the script is little changed.
- Muppets Tonight episode 211 includes a cameo by Bob Keeshan. He appears in character as Captain Kangaroo, wearing the red blazer he adopted during the 1970s and 1980s incarnation of the series.
- The book Would You Like to Play Hide & Seek in This Book With Lovable, Furry Old Grover? by former Captain Kangaroo staffer Jon Stone features Grover shouting "Mr. Greenjeans," the name of the Captain's chief sidekick.
