Toonfomercial: Remember Willy the Hillbilly? (1966)

Mountain Dew has been part of the Pepsi family since 1964. In 1966, Pepsi decided it was time for the product's mascot, Willy the Hillbilly, to appear in television ads for the soft drink. Country-bluegrass singer Grandpa Jones, three years before Hee Haw made him an icon, is the voice of Willy.

The ad campaign lasted just three years, but Willy returned a few years back-----in a video game.
