When I was in preschool, I believed in the man in the moon, which was on what would've been the first ever Wiggles CD, I think (it wasn't actually a song, it was a recording of one of the guys from the Wiggles talking about the man in the moon). I can still remember the bit where he says "The man in the moon has no hair!" which was the bit that my brother and I always laughed at. I believed that when it was night time, the man in the moon would have his light on, which was the reason why the moon glowed.
