Big Boat<br>Joe bought a brand new boat. He was very excited to show it off to all of his friends. In his excitement he dropped the keys, while signing the final papers. After a brief moment of fear, Joe found the keys on the dock. Joe breathed a sigh of relief as he headed home to see his friends.
