There is a man found dead in a circular mansion. The detective interviews the cook, maid, and babysitter. The cook said he couldn't have done it because he was preparing the meal. The maid said she couldn't have done it because she was dusting the corners. The babysitter said she couldn't because she was playing with the children. Who was lying?
The maid. There are no corners in a circular mansion.
You throw away the outside and cook the inside. You eat the outside and throw away the inside. What did you eat?
