Mark Evanier has all the details, but here’s the gist: it’s a snippet from a 1982 TV show where June Foray and Bill Scott (voices of Rocky and Bullwinkle respectively, along with craploads of other voices you know) trade off showing their stuff. Also, Evanier says that this the only footage he’s ever seen of William Conrad (Cannon, “The Fatman,” and narrator of umpteen other shows) doing narration on camera in his Rocky & Bullwinkle voice. And that means it’s pretty goddamn rare.
