Have you heard about the "gator aid? that was given to enlisted men in a Florida training camp during World War II? The daily training for those GIs included a run through an obstacle course. On the final stretch of the endurance test, they had to grab a rope and swing across a broad, shallow pool.
Under the blazing southern sun the water looked so inviting to the men that most of them soon developed a habit of making it only halfway across the pond'that is, until an enterprising lieutenant made it the new home for a large alligator. From that day on, the recruits left the ground 15 feet from the water's edge and fell sprawling in the dust on the other side.
