Physician, heal thyself indeed. In this comedy based on a novel by Ken Kolb, Dr. George Maitlin (Charles Grodin), a radio shrink, may be more troubled than his callers. He asks the station to hire an inept temp while he’s gone — that way, when he returns, he’ll be applauded. But an escaped mental patient (Dan Aykroyd) unknowingly takes the place of the temp the station hires and listeners actually like him! Walter Matthau co-stars.
