Duncan takes charge of a group of new students and tries to get in with them by playing the joker and recounting his own japes as a young student. Following an operation he is aghast to find that there is a spare body part in the bin. He fears that he has done something wrong but in fact it's the students playing a joke on him. He needs to get his own back.

Duncan competes with James Gascoigne to find an unusual case study to present at a forthcoming medical conference. Fortunately for Duncan he finds Mr. Andrews, a man whose heart is on the right hand side of his body - a rare case indeed. Unfortunately Mr. Andrews gets fed up with waiting around and wanders off whilst the eventual X-ray tendered is that of Sir Geoffrey.
