Comedian and author George Carlin has voluntarily checked himself into rehab for what he described as a growing problem with wine and Vicodin in an Entertainment Tonight interview. Carlin said he realized the problem himself and decided to take action quickly. Carlin's latest book When Will Jesus Bring the Pork Chops? (Hyperion) is a New York Times bestseller. It has also been banned at Wal-Mart.
