Paul Lynde as Dr. Paul Mercy joins Cleavon Little and a revamped supporting cast in the second season where Noland removes the appendix of a thief and Mercy searches the hospital for him.
In order to get an emergency crash cart for the hospital Dr. Noland creates a mythical heart patient that dies and then blames the death on a lack of equipment. The ploy appears to work until an autopsy is ordered on the fictional corpse.
Dr. Mercy initially turns down a promotion overseeing a chain of 23 hospitals, but rethinks the offer when he believes the staff does not want him to stay.
