Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE DONKEY AND THE OX
A man had just one ox so he yoked the ox together with a donkey and started
to plow. It was a humiliating arrangement, but unavoidable. When the work was
finished and the man was about to unyoke them, the donkey asked the ox, 'Who
do you think is going to carry the old man's tools on his back?' The ox said
to the donkey, 'The same one who always carries them!'
