I'm not what you would call a fan of GI Joe, but there were some amusing bits, especially around the period Steve Gerber was working on the show, like the episode "The Wrong Stuff", penned by Stanley Ralph Ross, where Cobra takes over the airwaves with pro-Cobra programming and swipes are taken at the state of TV and Saturday Morning Cartoons.
Then there was the Gerber-penned episode "There's No Place Like Springfield" where Joe operative Shipwreck finds himself waking up in a hospital, apparently suffering from memory loss; years have passed, Cobra has been broken up, GI Joe victorious and he's married with a daughter, living in a town called Springfield. But he starts wondering if he's going crazy, if he's losing it, if reality and illusion are getting mixed up in his head.
