The lion and the bear had caught a fawn.
"It's mine!" roared the lion.
"No, it's mine!" growled the bear.
Then they started fighting, slashing and tearing at one another until they collapsed on the ground, exhausted.
Meanwhile, a fox strolled by and saw the two of them lying there with the fawn between them. She ran up, grabbed the fawn, and carried it off.
The bear and lion both saw what the fox did but they didn't have the strength to stand up.
"Woe is us!" they said. "We did all the work, but the fox got the prize."
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 132 in the book, which is Perry 147.
