First toilette!

(Under the Tree of the Knowledge of Good and Evil.)
The serpent: “My dear pest, look at how you are arrayed!”
Eve: “It was Adam who lent me his fig leaf; it’s just that I carry it from behind.”
(Le Rire, Paris, 1906) (OK, this is a stretch, since it is not literally about the plague, but in a quirky way it seems to connect original sin with unpleasant modes of disease transmission. Perhaps I am committing the sin of Freudian overinterpretation. Or more likely my grasp of French idiom is not adequate to this case.)
