Secret Squirrel, Agent 000, was the James Bond of the rodent kingdom. Wearing a trenchcoat and laden with gadgets, the agent and his fez-wearing sidekick, Morocco Mole (who sounded a lot like Peter Lorre), worked for Double-Q Agency in England. Together they eluded such villains as Yellow Pinky, whose name somehow didn't instill as much fear as Goldfinger. But after all, this was Saturday morning.

Secret Squirrel first appeared as half of The Atom Ant/Secret Squirrel Show in 1965. After just over one season together, the two title heroes parted ways to star in their own self-titled shows. But less than a year later, ant and squirrel realized they worked better as a team, and The Atom Ant/Secret Squirrel Show was reborn for a final season.

The show would only last until 1968, but Secret Squirrel wasn't done gracing the small screen. More than 25 years later, the nutty agent could be seen in all-new episodes on Hanna-Barbera's Two Stupid Dogs, accompanied by Morocco Mole and a bull superior.
