Rashi, on Prov 26:8

“As he that casteth a stone into the heap of Mercury: so is he that giveth honour to a fool.”

“in a slingshot Heb. במרגמה fronde in French, Schleuder in German, in which the stone tied will not remain, for it is destined to be thrown, so is it with one who gives honor to a fool—it is not permanent. And our Sages (Hullin 133a) explained it homiletically as referring to one who teaches Torah to an unfitting student, that he is tantamount to casting a stone into a merculis.”
