I found similar one:

One day, a king and queen were watching the jester act like an idiot in their beautiful, round castle. In their castle, they had a maid, a cook, a jester, and a servant. The king and queen went to bed that night. The king woke up in the morning and the queen was dead. Somebody killed her. The king called a detective to town. The detective asked the maid what she was doing while the murder took place. She said she was sweeping the corners. Then he asked the cook. He said he was sharpening his knife collection. He asked the jester and he said he was watching Jersey Shore. Lastly, he asked the servant. The servant said he was too busy preparing the sofa for the next day. Who was it?
