The Iron Sheik was once the biggest villain in professional wrestling history and his feud with "The Real American" Hulk Hogan remains one of the most palpable sagas ever. These days, The Iron Sheik is a Twitter God whose hilarious, curse-filled off-the-wall comments are tailor-made for the medium. Both of those facts alone are more than enough to make me check out his new documentary "The Sheik" which is now officially available online.
