Osama's message to Bush

After numerous rounds of 'We do not know if Osama is still alive', Osama himself decided to send George Bush a letter in his own hand writing, to let the world know he was still in the game. Bush opened the letter which seemed to contain a single line coded message:
370H-SSV-0773H

Bush was baffled, so he e-mailed it to Condi Rice. Condi and her aides had no clue either, so they passed it onto the CIA. No one could solve the code there, so it was passed onto the FBI , and then onto NSA.With no clue as to its meaning they eventually asked help from Britain's MI6. Within a minute MI6 cabled the White House with this reply: 'Tell the President he's holding the message upside down'.
