Ventriloquist Paul Winchell was a fixture in the early days of television. If he wasn't headlining his own show, he'd be making the rounds on other programs, often with his sidekicks, Jerry Mahoney & Knucklehead Smiff.
In 1965, Winchell hosted a 1 hour syndicated variety show for children, Winchell-Mahoney Time. Thanks to the magic of videotape, Winchell appears as a number of different characters in the open, uploaded by Tapthatt2012. The voices would be recycled in later years. For example, the Charlie Chaplin lookalike's voice would later be given to Fleegle of The Banana Splits 3 years later, and still later would be applied to the Scrubbing Bubbles for some bathroom cleaner ads.
Here's the open, along with the closing credits:
Rating: None. Never saw the show.
