From his underground bunker, Saddam Insane sent George W. a letter in his own writing to announce that he is still in the game. Bush opened the letter and it contained a coded message:

370HSSV-0773H

George W. couldn't figure it out so he emailed it to Colin Powell. Colin and his aides had no clue either so they sent it to the CIA. No one could solve it so it went to the NSA and then to MIT and NASA and the Secret Service...
the list got longer and longer. Eventually they asked the Mossad in Israel for help.

Captain Moishe Pippick took one look at it and replied:

"Tell the President he is looking at the message upside down."
