I sincerely hope not, but this one is definitely a keeper:
After numerous rounds of official Washington denials consisting mainly of "We don't even know if Osama bin Laden 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 contained a single line of coded message:
Bush was, of course, baffled, so he e-mailed it to Condoleezza Rice. Condi and her aides had not a clue either, so they sent it to the FBI. No one could solve it at the FBI so then it went to the CIA, and then to MI6.
Eventually it went to the Mossad (Israeli intelligence) for help.
Within a minute Mossad emailed the White House with this reply:
"Tell the President he's holding the note upside down"...
