THE ASS AND HIS BURDENS
A pedlar had an ass. One day he bought a lot of salt and loaded the ass with it. It was a heavy load. On the way home, the ass stumbled while he was crossing a stream and fell into the water. The salt got wet and much of it melted. So, when the ass stood up, his load was much lighter. The pedlar, however, took him back to the city and bought more salt and loaded it up on the ass again. When they reached the stream, the ass lay down in it and then stood up, and his load was lighter again. But the pedlar understood the trick. He turned back to the city again but this time he bought a lot of sponges, and put them on the ass. When they came to the stream, the ass lay down again, but now the sponges soaked a lot of water, and when the ass got up, his burden was heavier than ever.
You should not play a good card too often.
