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

Bush opened the letter and it appeared to contain a single line of coded
message:
370HSSV-0773H

Bush was baffled, so he e-mailed it to Condi Rice. Condi and her 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 they eventually asked Britain's MI-6 for
help. Within a minute MI-6 cabled the White House with this reply "Tell the
President he's holding the message upside down."

LOL.

Yeah, I know I'm breaking rule number 4 (or was it 5) regarding trivial responses.

I used to make words like that on my handheld calculator back in High School

710 77345 (bah, 4 doesn't look like 'h' on computers like it does on calculators :))

I remember that old Shell Oil one, there was a joke involved in it, which I have long forgotten.
