Art Clokey, who invented Gumby and Davey & Goliath, tried marketing a toy named Moody Rudy, a Clark Gable lookalike (if Clark Gable had nothing between his neck and ankles) whose countenance could be messed around with to no end. And as we all know, a creepy toy deserves a creepy ad.
I can't imagine why it bankrupted Clokey.
This is a perfect example of truth in advertising - my mind has indeed been turned into coffee grounds. Whether by Rudy himself or that vibrating butt he's riding at :48, I'll leave up to you.
