After numerous rounds of "We don't know if Osama is still alive," Osama himself decided to send Ted Kennedy a note in his own handwriting to let him know he was still in the game.

Kennedy opened the note, which appeared to contain a single line of coded message: 370HSSV-0773H.

Kennedy was baffled, so he E-mailed it to John Kerry. Kerry and his aides had no 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 the NSA. With no clue as to its meaning, the FBI finally asked Marine Corps Intelligence for help.

Within a few seconds, the Marines cabled back with this reply: "Tell Kennedy he is holding the message upside down."
