When I was a kid, nearly 60 years ago. the Wienermobile, complete with Little Oscar, visited a grocery store near me. The gang all trooped down there, excited to meet such an illustrious personage.
Boy were we crushed. Little Oscar turned out to be a very grumpy and impatient man with no interest in kids whatever. I'm permanently traumatized from the experience and would have to choose the Rolling Nut.
They're both about equally ugly, IMO.
