No longer behind bars, Martha is back on top of her domestic empire - but not her manners. Martha Stewart Living Omnimedia Inc. just posted its first quarterly profit in two years. But Martha's still not happy. She blames the failure of her Apprentice show on competition from Donald Trump, who she claims she was supposed to "fire"at the beginning of the season.
