Another anecdote: I have another email address (first_last@isp) and my last name is one of those that are very common but exist with several different spellings. One day I got a message from a freshly-wed lady, and she intended to send the mail to her husband. From the mail it seemed like she took his last name when they married, which made it even funnier that she mistyped it in the email address she sent the mail to. :)
