After numerous rounds of 'We don't even know if Osama is still alive',  Barrack Obama has now been telling everyone he will capture Osama Bin Laden when elected.'

So, Osama Bin Laden himself decided to send Barrack Obama a letter in his own handwriting to let him know he was still in the game.

Obama opened the letter and it contained a single line of coded message:

370H-SSV-0773H

Obama was baffled, so he e-mailed it to Howard Dean.

Dean and the DNC and his aides had no clue either, so they sent it to Joe Biden.

Joe Biden could not solve so it was sent to the FBI and the CIA.

Eventually they asked John McCain and his Staff to look at it.

And within a minutes McCain's Staff e-mailed Obama with this reply:  'Tell Obama he's holding the message upside down'

What's erotic about this joke?
