Perry's Index to the Aesopica
Fables exist in many versions; here is one version in English:
THE FOX AND THE CROCODILE
The fox and the crocodile were disputing about their pedigrees. The crocodile
was proudly enumerating the eminent qualities of his ancestors, and when he
said that they had been the highest ranking athletic officials, the fox remarked,
'My dear sir, even if you had not mentioned it, the mere condition of your skin
is evidence enough that you have suffered long years of athletic sports out
of doors in the sun!'
