The fox took a look at the worm, and she was not impressed. The worm's skin was ugly and wrinkled, and as the worm moved he twisted and squirmed.
"O Doctor," said the fox, "you need to heal yourself first before you boast about your medical skills."
Inspired by: Mille Fabulae et Una, a collection of Latin fables that I've edited, free to read online. I am not translating the Latin here; instead, I am just telling a 100-word version of the fable.
Notes: This is fable 57 in the book, which is Perry 289. There's a similar fable about a fox and a frog.
