After mumerous rounds of "We don't even know if Osama is still alive",
Osama himself decides to send George Bush a letter in his own handwring
to let him know he was still in the game.
Bush opened the letter and it appeared to contain a single line of coded
message:

37OHSSV - O773H

Bush was baffled, so he sent it to the F.B.I.
No one could solve it at the F.B.I. so it was sent to the C.I.A., then
to the N.S.A.

With no clue as to its meaning they sent it to the British MI6 for help.
Within a minute, MI6 emailed the White House with this reply:

Tell the President he's holding the message upside down.

pmsl good one

Cute!
