A childhood belief about hair

When I was in seventh grade, I had my first boyfriend. We were in science class one day, and I noticed that a strand of my hair had fallen out. He quickly took it and placed it on his head, then proceded to attempt to answer a difficult question, only to be devistated when he could not answer it correctly. I was a better student than he was, and he was convinced that putting a strand of someone else's hair on your head, you would gain their intelligence!
