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 appeared to contain a coded message:
370HSSV-0773H

Bush was baffled, so he e-mailed it to Condi Rice. Condi and her
aides had no clue either, so they sent it to the FBI. No one could
solve it so it went to the CIA, then to the NSA.
With no clue as to its meaning, they eventually asked Britain's MI-6
for help. MI-6 cabled the White House:


"Tell the president he's holding the message upside down."
