From season 2 of Batman: The Animated Series:
Batman (Kevin Conroy) has to rescue one of his childhood benefactors, Dr. Leslie Tompkins (Diana Muldaur), who's been conscripted to aid the Crime Doctor for an important operation. You see, Dr. Matthew Thorne, aka the Crime Doctor, is the brother of mob boss Rupert Thorne (John Vernon, ex-Delta House). Rupert needs heart surgery, and since he already has brother Matt under his thumb, he arranges for Leslie to be Matt's nurse.
Joseph Campanella guest stars in "Paging The Crime Doctor":
In memory of Campanella, who passed away last week at 93.
