The Fox and the Billy-Goat

A fox, having fallen into a well, was faced with the prospect of being stuck there. But then a billy-goat came along to that same well 
because he was thirsty and saw the fox. He asked him if the water was good.
The fox decided to put a brave face on it and gave a tremendous speech about how wonderful the water was down there, so very  
excellent. So the billy-goat climbed down the well, thinking only of his thirst. When he had had a good drink, he asked the fox what
he thought was the best way to get back up again.
The fox said:
‘Well, I have a very good way to do that. Of course, it will mean our working together. If you just push your front feet up against
the wall and hold your horns up in the air as high as you can, I will climb up on to them, get out, and then I can pull you up behind me.’
The billy-goat willingly consented to this idea, and the fox briskly clambered up the legs, the shoulders, and finally the horns of 
his companion. He found himself at the mouth of the well, pulled himself out, and immediately scampered off. The billy-goat shouted
after him, reproaching him for breaking their agreement of mutual assistance. The fox came back to the top of the well and 
shouted down to the billy-goat:
‘Ha! If you had as many brains as you have hairs on your chin, you wouldn’t have got down there in the first place without
thinking of how you were going to get out again.’

It is thus that sensible men should not undertake any action without having first examined the end result.
