It took a gallery full of bizarre art and a questionable head injury, but Donald Trump (search) finally axed Omarosa Manigault-Stallworth (search) on Thursday night's "The Apprentice."

"Omarosa had a huge chip on her shoulder, she felt she was superior to the other people," Trump said, effectively pulling the plug on the most disliked reality-TV star since Richard Hatch on "Survivor."

The contestants on "The Apprentice" (search) had long complained that Omarosa was dramatic, condescending and difficult to get along with. Moments before she was fired, the teary-eyed 29-year-old political consultant stormed into Trump's boardroom to plead her case.

It didn't work.

Earlier that day, the last straw was a clash with teammate Heidi Bressler (search) when, in the middle of an important task, Omarosa demanded to go in a deli and have a lengthy lunch. She fought with Bressler, who told her there was no time.

"She always has a headache when it's task time. When it's reward time, she's fine," Bressler said. "Omarosa's an absolute lunatic bitch."

On last night's episode, Trump challenged the contestants to sell works by emerging artists.

The losing team, Protégé, chose to risk selling more expensive but extreme-looking pieces with bloody, disembodied heads and other strange images.

None of the contestants really understood the art and had trouble selling it to gallery patrons - only one piece worth about $800 was sold. The winning team, Versicorp, opted to sell less expensive abstract modern art inspired by nature and had no problem selling more than $13,000 worth.
