I was told a scary story by my babysitter once, about a girl who passed out in front of her microwave while it was heating something... and the girl's internal organs got all fried. To this day, I can't stand in front of the microwave while it's heating anything, I always stand to the side if I'm waiting. Funny thing, my little brother has the same inherent belief that microwaves are dangerous to stand in front of. We both just can't get the image of dangerous rays coming out to fry us, even though we're now both in our 20's.
