After numerous rounds of "We don't even know if Osama is still
alive", Osama himself decided to send George W. a letter in his own
handwriting. Bush opened the letter and it appeared to contain a
coded message:
37OHSSV-O773H
Bush was baffled, so he emailed it to Colin Powell. Colin and his
aides had no clue either - so they sent it to the FBI. No one could
solve it so it went to the CIA, then on to NASA, the to the Secret
Service. With no clue as to it's meaning, they eventually asked
Canada's RCMP for help.
The RCMP cabled the White House as follows:
"Tell the President he is looking at the message upside down."
