Twelve candidates, nearing completion of their studies, were led into the garden for their final exam before becoming a monk. Each stripped naked and tied a small bell to his penis. “Any man whose bell rings has not reached an adequate state of purity,” announced the abbot. A beautiful nude woman was brought out to dance before each of them in turn. She did her best to excite them, but the first candidate had no reaction, nor did the second, nor the third. But the final monk’s bell rang so loudly it fell off and clattered to the ground. Embarrassed, he bent down to pick it up… and all the other bells went off!
