370HSSV-0773H

After numerous rounds of "We don't know if Osama Bin Ladin is still alive," Bin Ladin himself decided to send George W. Bush a note in his own handwriting to let Bush know that he was still in the game.

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

Bush was baffled, so he E-mailed it to John McCain. McCain 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 Barack Obama for help. Within a few seconds, Obama cabled back with this reply: "Tell Bush that he is holding the message upside down."
