Get Smart: Our Man in Toyland (1965)
Get Smart was an espionage parody about counterintelligence agents battling an organization of international spies and criminals. Mel Brooks is credited as a co-creator, so it probably shouldn't be surprising to hear this show completely holds up. It's bizarre and quirky, and even more than fifty years later, the antics of Don Adams (who'd later voice Inspector Gadget) remain hilarious. "Our Man in Toyland" was only the fourth episode aired. It should be noted that its inclusion here is somewhat questionable. Logically, the episode must take place during the holiday season, but the show is intentionally illogical to the point, I'm not sure the justification was anything more than a joke. The premise of the episode is that KAOS, the aforementioned SPECTRE stand-in, is using a department store as a front to sneak state secrets out of the country. CONTROL (a.k.a.: the good guys) send in a handful of agents to determine how they're accomplishing this
