John and two of his friends, Bill and Bob, had gone fishing for a week and each of them had brought his own boat. John had paid for his campsite a week in advance, but Bill & Bob had only paid for the first night. While they were all out on the water, something came up that was going to cause John to have to go back home for the week. He told Bill and Bob that he would give his campsite to the one whose boat got back to the dock LAST. Bill and Bob started for the dock, going slower and slower, but eventually neither one would even move. The Game Warden came by and asked why the two boats were just sitting there not doing anything. When Bill and Bob explained what was going on, the Game Warden made a suggestion, and afterwards Bill and Bob went wide-open-throttle heading back for the dock. What did the Game Warden tell them?
