Pythagoras, apostle of the hypotenuse, forbade his followers to eat beans. Why? Because they reminded him of testicles and because they produce flatulence. Eating symbolic testicles was metaphorical cannibalism of a particularly noxious sort: patiophagy, fatherfeeding. Farting was an even more obvious transgression. We moderns don’t like it any more than Pythagoras. Consider the ironic childhood jingle:
Beans, beans, the musical fruit, The more you eat, the more you toot. The more you toot, the better you feel, So let’s have beans at every meal.
