There are two men walking in the desert, but neither knows each other. One of them is dying of thirst and the other has a full jug of water. The man with the jug offers the man a drink, but only if he follows three simple rules.
Rule 1: He cannot have the jug, because it is his only one.
Rule 2: He cannot remove the cork from the spout and drink this way.
Rule 3: He cannot poke a hole into the cork or the jug.
So, the thirsty man accepted his rules and then, he finished his drink and left. How did he do it?
