Stupid things you thought as a kid

OK, this is something REALLY silly...

My grand father was bald at the front and had little hair on the back side of head...One day, I asked him where all of his hair go and he replied," Once, I was asleep in this garden when a goat came by and ate all my hair up." Obviously, he was joking but I took it 100% seriously and continued to think it was true until I was 10-11..
