That reminds me of the time I worked for a company that got massively infected cos the "Head of IT" (who incidentally knew nothing about computers) opened an "I love you" email and sent it to every one in the company.
He then sent out a diktat saying that it would be a sackable offence for anyone opening the "I love you email" (that his incompetence had produced) and exacerbating the problem. You couldn't make it up!
