Vienna wants to sell hotdogs, not toppings. It's hard to imagine how you could even see the hotdog itself on one of their signs if they covered it with all of the toppings people are mentioning. I don't think tomatoes or pickle spears started coming into common usage until sometime in the 70's. Before that it was usually just mustard, relish, onions, and sport peppers.
What if the Hokey Pokey really IS what it's all about?
