This episode assembled as guest stars three of the most memorable TV doctors for better or worse, Vince Edwards who starred in the title role of Ben Casey (1961), Chad Everett who starred as Dr. Joe Gannon in Medical Center (1969), and Larry Linville who as Dr. Frank Burns was the only actual quack among the medical staff of the 4077th on M*A*S*H (1972). This was the only time any of the three late actors worked together, playing comical versions of themselves as they take their TV medical training too seriously.
