Dr. Thompson was an excellent physician. All of his former patients, when asked about him, would fairly gush, calling him "an absolute angel", and "a miracle worker". It seemed there was no disorder, illness, or deformity that Dr. Thompson could not fix.
Dr. Thompson, however, had one minor flaw-- he suffered from a rare but serious disorder himself: an acute fear of zombies. So, while he was exceptionally adept at caring for his living patients, the sight of a flatline triggered blind panic. Without fail, after a patient had been confirmed deceased (a consequence of natural and unavoidable causes, of course), Dr. Thompson would turn to his nurses, shouting, "SHOOT IT. SHOOT IT IN THE HEAD!" before turning back to the grieving family to offer his sincere condolences for their loss.
