"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:
370H-SSV-0773H
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 Australia: Intelligence (ASIO) for help. Within a minute, ASIO emailed the White House with this reply:
'Tell the President he's holding the message upside down.'"

An elderly couple, Margaret and Bert, moved to Texas . Bert always
wanted a pair of authentic cowboy boots, so, seeing some on sale, he
buys them and wears them home.
Walking proudly, he goes into the kitchen and says to his wife,
'Notice anything different about me?'
Margaret looks him over, 'Nope'.
Frustrated, Bert storms off into the bathroom, undresses, and walks
back into the kitchen completely naked except for the boots. Again,
he asks, a little louder this time, 'Notice anything different NOW?'
Margaret looks up and says, 'Bert, what's different?
It's hanging down today, it was hanging down yesterday, it'll be
hanging down again tomorrow.
'Furious, Bert yells, 'AND DO YOU KNOW WHY IT'S HANGING DOWN
MARGARET?'
'Nope', she replies.
'IT'S HANGING DOWN, BECAUSE IT'S LOOKING AT MY NEW BOOTS!!!!'
Margaret replies... 'Shoulda bought a hat, Bert.
Ya shoulda bought a hat.'
