The scientist and the farmer.

A scientist entered a train going to New york. His cabin also had a poor farmer in it. To pass the time, the scientist decided to play a game with his co-traveler. "i will ask you a question and if you get it wrong, you have to pay me one dollar. Then, you ask me a question, and if i get it wrong, you get 10 dollars. Ask me a question first. " The farmer, after a while asked, "what has three legs, takes 10 hours to climb a palm tree and 10 seconds to desend?" The scientist was confused and for long time, he could not answer the question. Finally, when they came to the station where they were to part, the scientist brought out 10 dollars and gave it to the farmer, saying, honestly, i don't know. But what has three legs, takes 10 hours to climb a palm tree and ten seconds to decend? The farmer after collecting the 10 dollars, replied, " i don't know either. "He then removed one dollar from the money and gave it to the scientist, who felt so bad that the farmer had swindled him.
