She asked him why he wanted the leanest one. He replied: "Because I
am sorry for him, for he always gets the worst beating. I will have
that one, and no other."
So she said: "Well, I will give him to you, if you must have him,
but I will give you this fat one too. You can ride on his back home
and lead the lean one with you."
He mounted the fat horse and rode off. But when they were drawing
near to the gate, the lean horse said: "Get down from that horse and
mount me, or you will be the worse for it."
So he jumped down from the fat horse and mounted the lean one.
