The Flintstones

Itty Bitty Fred (5x3)

:

Inventor Fred comes up with a weight-loss potion that doesn't just shed pounds, it drastically reduces Fred's size. Capitalizing on the weird situation, Barney goes on "The Ed Sullystone Show" as a ventriloquist, with Fred acting as his dummy. But during the act, Fred returns to his normal size, and they are thrown off the show.
