Rocket Robin Hood (1966)

Another in the so-bad-it's-good category (although that doesn't mean you can watch more than one episode simultaneously). Rocket Robin Hood was courtesy Krantz Animation. This series ran in syndication from 1966-69 and is still a common sight on Canadian television to this day (as IMDB comments indicate). Watch incidental moments from the show here, here, here, and here. It is said that Ralph Bakshi wrote and directed several episodes just as he did for the Spider-man series of the period.
