My brother told me when I was four (he's six years older than me) that during nap time his teacher would walk around with a board with nails in it. She would hold the board close to your face to see if you were sleeping. So when I started school I believed the same thing and would never let myself fall asleep during nap time. My brother is 30 now, and still says it really happened. I still kind of believe him.
