Got this in email:-
The Iranian President sent a letter to his US counterpart on Monday  but
would not reveal its contents. The US president 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 NSA. With no  clue as to its meaning
they eventually asked Britain's secret intelligent service 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."
