We had medical ethics. Leading a graduate student, she tells a case from practice: In short, a lady with a cat came to us and said, "Snap my cat, a witch has settled in it." 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 injected a salt solution into the cat and let go home with Madame. Madam left happy, and the cat looked at everyone as if they were fools.
