Letter from Bin Laden?

After numerous rounds of "We don't know if Osama Bin Laden is still alive", Osama decided to personally send President Bush a letter in his own handwriting to let him know he was "still in the game".

Mr. Bush opened the letter, which contained a single line of "coded" message:

370HSSV-0773H

Mr. Bush was baffled, so he sent copies to his Chief of Staff, and several Secretaries, including Condi Rice and Donald Rumsfeld. Their assistants and aides had no clue as to the meaning or translation of the code, so it was sent to the Federal Bureau of Investigation, then to the CIA and also to NASA. With no clue to the translation, they eventually asked Israel's MOSAD for help.

Within a minute, MOSAD cabled the White House with this reply:

"Tell the President he is holding the message upside down."
