1960's intro to judo by The Funny Company
Paul Virtue pointed me to this. It's an episode of an old educational cartoon called The Funny Company. I recommend skipping the introductory cartoon-y stuff and jumping to the 3-minute mark.
The YouTube caption says:
The Funny Company,originally commissioned by Mattel Toys, featured mini educational films, cleverly sandwiched within each animated story, to help illustrate the theme of the cartoon. This innovative 1963 series was developed by producer Ken Snyder (Roger Ramjet, Skyhawks, Hot Wheels) in response to a 1961 speech by the FCC chairman urging more cultural and educational children's programming.
