Panchatantra Singing Donkey

tale:panchatantra_singing_donkey

A donkey raiding a cucumber field by night grows so happy that it wishes to sing, and brays despite its jackal friend's warning that the noise will bring the guards. It sings; the watchmen come and beat it well. Moral: there is a time to be silent, and the fool who must perform finds it too late. — Panchatantra (attrib. Vishnu Sharma)
