Riddle: A babysitter came over one day to babysit 10 children. She decided to give them a snack. In a jar there were 10 cookies. She wants to give each one a cookie, but still keep one in the jar. How will she do it? (WITHOUT BREAKING ANY COOKIES-EACH CHILD HAS TO GET A WHOLE!)
Answer: She hands the 10th child the jar with one cookie left in it.
