I just checked the hotmail account for the PBB Dead Letter Office. There was a new email in the ol' coffin-shaped inbox (kidding, geez), so I clicked to open.
The subject line was "Dealing with a messy inbox?"
The email was from MSN, the creator of the email account...
Sent to a 10.0 Gb email account with an empty inbox, and one (1) total saved email, stored every-so-neatly in its electronic folder.
That's funny, is what that is.
