A crow, having snatched some meat, sat on a tree. And a fox seeing him, and wishing to obtain the meat, stood and praised him as well-proportioned and beautiful — also saying that he should indeed be king of the birds, and that this would have happened, if he had a [good] voice. And wishing to show her that he too had a voice, he threw off the meat and shouted loudly. And having run to him and snatched the meat, she said: "O Crow, if you had brains too, nothing would be lacking for you to be king of everything."
The word is opportune for a foolish man.
