Hahaha, it's mostly a super funny situation. As it's known, I've worn a lot of wigs during my ... Well I still do. Anyway, so in a couple of cases they have slid off, mostly because someone just happens to pull it or something like that. So people just stare like they haven't ever seen a wig before and their faces are downrite hilarious.
Most people are completely alien to the idea of wearing wigs. They seem to feel it's something only bald people do I guess?
