You know how, at least in the UK and Ireland, flammable objects such as clothes and books have labels reading "Keep Away From Fire"? Well, when I was little, I thought Keep Away From Fire was a brand and everything with the label was connected in some way. I think I first saw it on another kid's Spider-Man costume, so I wondered how Spider-Man fit in to the brand.
