Three turtles are lined up in a row. The first turtle said, "I've got 2 turtles behind me and no turtles in front of me." The second turtle said: "I've got 1 turtle behind me and 1 turtle in front of me." but the last turtle surprised the other two and said, "I've got 2 turtles behind me and 2 turtles in front of me."
How is that possible?
