Stock Market Explosive Diarrhea

The near 1,000 point drop remains another unsolved American mystery.  Nobody knows what happened and those in the know of course aren't talking.  Rumors have it that some trader at Citigroup might have inadvertently punched in billion instead of the intended million.  Now I ain't part of Wall Street so I don't know if this scenario is plausible or not.  Or we can just blame it on the Greeks or the British election.  In any event, maybe somebody somewhere has made tons of money out of this abrupt explosive stock diarrhea.
