I am of a different mind ten times in the course of a day. But I resist the devil, and often it is with a fart that I chase him away. When he tempts me with silly sins I say, “Devil, yesterday I broke wind too. Have you written it down on your list?” -Martin Luther
So you see how farts may serve a functional purpose in pastoral theology. If one is tempted, then crack off a loud one (says the good doctor).
