When I was young my cousins told me that when you had an ear ache, it was because there was an earwig inside of your ear. I had always had problems with my ears, and still do, so that scared me. Especially when one of my youngers brothers friends actually HAD had one in their ear as a baby.
I'm still scared of earwigs to this day, although I know they are not in my ears!
