In January, he was arrested for failing to appear in court after a domestic disturbance. His health has also faltered -- Coleman suffered seizures in January and again later February on the set of "The Insider."
Nine days later, in what is believed to be his final television appearance, Coleman lashed out at "The Insider" guest panelist Lisa Bloom when she asked if he ever lay hands on his wife.
"You go somewhere and drown yourself in the ocean!" Coleman shouted.
"Is that the way you talk to your wife?" responded Bloom.
"Yes, if I have to!" exclaimed Coleman. "If I need to, but I don't. I don't know about you, I don't care about you! If you get hit by a bus I am not going to care!"
In a radio interview last year Coleman reflected on his life, and the parents who he accused of stealing three quarters of his television earnings.
"I am still bitter about it," Coleman said. "It still hurts, it still hurts. You do midget mascots to pay the mortgage."
