Jataka Ass Lions Skin

tale:jataka_ass_lions_skin

A trader dresses his ass in a lion's skin and turns it loose to graze by night in others' fields, where folk flee the supposed lion. All goes well until the ass, hearing other asses, brays in answer; the villagers know the voice, strip off the skin, and beat it. Moral: the disguise is undone by the voice within. — Jataka tale
