"A poor woodcutter found a baby in the forest and adopted him. But how should he feed the child? He prayed to God, and a miracle happened: The woodcutter grew breasts and could nurse the child."
A student:
"But why should god make woman's breast grow on a man? God could have sent a purse with gold, so the woodcutter could have hired a nurse."
The rabbi responds:
"Wrong! Why should God spend money, if he can manage with a miracle?"
