The Dream Team (1989)

A comedy about what happens when four mental patients -- an aggressive sociopath, a Jesus freak with a penchant for removing his clothes at inopportune moments, an obsessive-compulsive with a neatness fetish, and a young man who can communicate only in baseball-speak -- are set free in Manhattan. It all begins when their doctor takes them on a day-trip to see a baseball game at Yankee Stadium. When the doctor is abducted after witnessing a murder, these four crazies are on their own. Each takes advantage of his freedom to pursue his own off-the-wall concerns before banding together again to rescue the doctor.
