I had this one sent to me today:
Osama Bin Laden 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 baffled, so he e-mailed it to Condoleezza Rice. Condi and her aides hadn't a 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 MI6 and Mossad. Eventually they asked ASIO for help.
Within a minute, ASIO emailed the White House with this reply:
'Tell the President he's holding the message upside down.'
