After numerous rounds of "We don't even know if Osama is still alive", Osama himself decided to send George Bush a letter In his own handwriting to let him know he was still in the game. Bush opened the letter and it contained a single line of coded message:

370H-SSV-0773H

Bush was baffled, so he e-mailed it to Condoleezza Rice. Condi and her aides didn't have a clue either, so they sent it to the FBI.

No one could solve it at the FBI so it went to the CIA, then to Australian Intelligence (ASIO) and Mossad.

Eventually they asked MI6 for help.

Within a minute MI6 emailed the White House with this reply:
"Tell the President he's holding the message upside down."
