In what might be the worst day at the office ever, Clifford Etienne went completely bonkers at his check cashing business. Frustrated with his employees for "not working fast enough," the boxer fired a round into the ceiling with a handgun. When the police arrived, Etienne tried to escape by carjacking two different vehicles with children inside before being apprehended.

Etienne was charged with attempted first-degree murder of a police officer, two counts each of armed robbery and second-degree kidnapping. The man who's famous for being knocked out by Mike Tyson in 49-seconds will spend the rest of his life in prison.
