Answer a fool according to his folly, or he will be wise in his own eyes.

3A whip for the horse, a bridle for the donkey, and a rod for the back of fools. 4Do not answer a fool according to his folly, or you will be just like him yourself. 5Answer a fool according to his folly, or he will be wise in his own eyes. 6Whoever sends word by the hand of a fool cuts off his own feet and drinks down violence. 7The legs of a lame man hang useless, and so does a proverb in the mouth of fools.
