Breakfast of Champions

Rabelais, Gargantua and Pantagruel, I.25 (tr. J.M. Cohen):

For note that grapes and fresh cake for breakfast is a dish for the gods, especially pineau-grapes, fig-grapes, muscatels, great black grapes, and purgative grapes for those whose bowels are constipated. For these make them squirt the length of a hunting spear; and often when a man means to fart he shits himself; from which these grapes get the name of wet-farters.
