Oh, yes ketchup. It is not just a topping for various food, but I guess it can be a "toy" in some way. I was at McDonalds the other day to get something to eat and I decided to go in. As I was standing in line, I look around and there is this mother with her young daughter having lunch. And her daughter was smearing ketchup all over the table, clapping her hands in it, and licking it off of her hands, food, and table. It was the worst thing I ever seen. And all the mother said was "Oh, you are silly. You just love ketchup.", I was disgusted. Even though I like ketchup myself and put it on a good amount of foods, the smell and thought of playing it is just disgusting.
