This was America's longest-running children's television series until 1999, when Sesame Street (1969) surpassed it. It remains the longest-running children's series on U.S. commercial television.
One of the running gags on the show was Bunny Rabbit or Mister Moose causing ping pong balls to fall on the Captain.
Most network shows were broadcast in color by the mid 1960s. CBS did not convert the Captain's early morning program to color until 1967.
One of the show's long-running gags was the "Ping-Pong Ball Drop", instigated by the telling of a joke (usually a knock-knock joke) by Mr. Moose, in which the punchline included the words "ping-pong balls". At the mention of those three words, a shower of ping-pong balls was released from above on the Captain.
