Chain letters
Man these thing are annoying, they always say if you break them then some 'ghost' chick will come and kill you which is a lie of course, but instead of threatening people they could just ask them nicely if they could send it. I remember one was from 'the flute girl' and it said if you don't send it in the next minute the flute girl will kill you. Another one said 'I have no nose, no ears, and no hair, and no eyes, If you do not send this in the next minute I will be standing over your bed tonight with a butcher knife and kill you. One silly one said not to brake it because it had been going since 1929, but there were no computers in 1929!
