Two men were sentenced for 20 years to be in a single room with only one wish in each 10 years. The first man asked for as many books as he can put in his room, so he can read these books in next 10 years alone. The second one was a smoker as a habit. He asked for enough quantity of cigarettes for next 10 years. After giving the books and cigarettes, guardians closed and locked their doors. 10 years later it was the time to ask to the prisoners for their second wish for last 10 years. The first man asked for books again and a reading-glass. Then, they opened the door of the second prisoner and found him with all cigarettes and he was insane. They asked him for his second wish for the following 10 years. "Lighter !!!...Lighter!!!" he said with a screaming voice.
