Kevin O'Leary is back in the red chair. He's one of North America's most successful business entrepreneurs - but he's not too worried about being liked. In fact, he's made a media career out of his outspoken nature: on 'Dragons' Den', Kevin is a tough critic. He's more than willing to be combative in conversation with Amanda Lang on 'The Lang & O'Leary Exchange'. And his larger-than-life personality serves him just fine on ABC's 'Shark Tank'. Also on the show: the always hilarious Mr. Pat Thornton.
