Four employees at a group home for the developmentally disabled in Southampton are accused of running a "fight club" with their charges, egging on two men in their 50s to battle until one was knocked over in his wheelchair, and congratulating the winner with a "double high-five."

Three of the accused were in Southampton Town Justice Court Thursday and pleaded not-guilty. The fourth was due in court today. They face felony charges of endangering the welfare of an incompetent or physically disabled person.

One shot video, which authorities say shows the other three laughing and having a grand old time. Here's hoping that, if guilty, they make some nice new friends in jail.
