Gallant, sprightly, and jovial; resourceful, bold, and adventurous; resolute, tall, and thin, with a handsome nose,which he attributed to his nurse's soft breasts, Friar John was a "grand mumbler of matins, dispatcher of masses, and polisher off of vigils and, to put it briefly, a true monk if ever there has been one since the monking world monked its first monkery." His breviary was his bottle, and his bottle, his breviary.

When Friar John was asked by Panurge for his advice on marriage, he responded by insulting his testicles in173 different ways. The Friar twitted Panurge about his advancing years and the consolations of a cheating wife, with whom he was certain to hook up. Friar John advised Panurge that the only remedy for a wandering woman was Hans Carvel's ring, of which, if you are impatient to hear, consult Chapter 10 of the Third Book.
