When I was about 4 or 5, I used to belive that breadsticks were actually the leftover crusts of pizza that someone already ate. To confirm this belief, when my uncle came over one time, with some breasdsticks, I asked him what happened to the pizza. He told me that my cousins had eaten it earlier, therefore confirming my belief that breadsticks were really the leftover crusts of pizza that someone already ate.
So all I could think of was the fact that I was eating something that someone's mouth has already been near...
