Camel Power
One day, this old man in the desert decides to buy a camel that didn’t have to drink every hour like his old one did. He then stops at the Market.
When he gets there and asks for a camel, one man instantly comes and offers him a camel that could drink 50 liters of water and wouldn’t be thirsty for a long time. But he says he wanted more.
Then this other man offers him one that drinks 60, and another that drinks 70, and so on until 120, then this guy says his camel drinks 2 tons of water three times a year. The old man asks him how.
Then the merchant tells him to hold the camels’ head under the water. He then takes two big bricks and bangs them together on the camel’s dick.
