The wonder of e-mail has revolutionised communication.

Last Thursday a bank employee in Sweden sent an internal sex-joke to a coworker. ("I've had sex in office...") Unfortunately, she sent it not to her coworker but to someone with the same name, who didn't realise that it was just a joke. Instead she forwarded it to her friends. Today, less than a week later, the majority of Swedish e-mail users have received it, including the original posters full name and place of work.

Something worth thinking of before you hit the Send button. You could become (in)famous over night...
