I grew up believing that the microwave would blow up if someone put metal in it. Thanks to the Myth Busters, I now know this isn't true... But when I was a kid, I'd either run out of the house screaming or run to my parents' bedroom (the furtherst room away from the kitchen [my bedroom was on the other side of the wall from the microwave, so I couldn't hide there!]) and hide, waiting for either the microwave or the whole house to blow up whenever my mom microwaved a bowl of soup with a spoon in it.
