I'd all but forgotten about the Oscar Mayer Wienermobile until Radley Balko posted news about it crashing into a house in Wisconsin. For some reason I was disappointed to learn Oscar Mayer has 6 wienermobiles. I always figured there was just one, silly me.
I actually saw one with that supposed "Little Oscar" guy decades ago down in Southern California. I don't remember where exactly. I was real young. It was in some parking lot somewhere and the little guy that used to drive it and be on the TV ads waved at me.
I guess the company still uses those things and gives drivers special training and education on hot dogs. More on wienermobiles here. They have changed through the years.
