We had medical ethics. A postgraduate student, tells a case from practice:

Shortly afterward, a lady with a cat came to us and said, "Sleep my cat, a witch has settled in her." And seriously so. Well, we and the trainee poured water into the test tube, said it was holy water, sprayed on the cat (the cat was very dissatisfied). The trainee read Goethe's poems in German (well, Madame German didn't know), then they infused the cat with a solution and let go home with Madame. Madam left happy, and the cat looked at everyone as if they were fools.
