Surgery to be done by a veterinarian specializing in reptiles.
Maybe surgery done by a brain surgeon who said at the end of the procedure? Has anyone seen my anal scissors I used in the operation?
From the back of the operating room came a reply of one word, “Oops”.
Doctor: What do you mean “Oops”?
Voice: They are still in him.
Doctor: Never mind. He had nothing to damage in the first place!
I figured he would need a medical specialist who deals with the undead.
