The "greed is good" money man who everyone loved to hate in the movie Wall Street has turned a new leaf. He's now working for the FBI, reports MSNBC. "Gordon Gekko," aka Michael Douglas, is doing a public service announcement for the FBI cautioning consumers to be alert, warning Wall Streeters to stay on the straight and narrow, and urging snitches to turn in their law-busting buddies. Money-grubbing Gekko ends up in prison for scamming innocent investors. "The movie is fiction, but the problem is real," warns Douglas, who urges that Wall Street baddies be reported at www.fbi.gov.
