Bin Laden's message

After numerous rounds of 'We don't know if Osama Bin Laden is still

handwriting to let him know he was still in the game. Bush opened the
letter which just appeared to contain a single line of coded message.

Bush was baffled, so he emailed it to Condi Rice. Condi and her aides
had no clue either, so they sent it to the FBI. No one could solve it at
the FBI so it was then passed to the CIA, who in turn sent it to NASA.
With no clue as to its meaning they eventually asked Britain's MI-6 for
help. Within a minute MI-6 emailed the White House with this reply.
