When a mother concerned about her teen daughter drinking, smoking and causing chaos admits to Dr. Phil that her new husband treats her daughter differently than his own daughter, and even wants her daughter out of the house altogether, Dr. Phil gets personal. "I've always had the attitude: If my children aren't welcome, I ain't welcome," says Dr. Phil, who has two grown sons. "You mess with them you're messing with me. If somebody's not OK with them, they might as well spit in my face, because we're done."
