     On a hot summer day in south Florida, a little boy decided to go for a swim in the old swimming

hole behind his house.In a hurry to dive into the cool water, he ran out of the back door, leaving behind

shoes and shirt as he went.

     He flew into the water, not realizing that as he swam toward the middle of the lake, a crocodile was

swimming toward him.His mother in the house was looking out of the window and saw the two. In great

fear, she ran toward the water,shouting to her son as loudly as she could. Hearing her voice, the little boy

became alarmed and made a U-turn to swim to his mother. It was too late. Just as he reached her, the

crocodile reached him.From the shore, the mother caught her Iittle boy be the arms just as the crocodile

snatched his legs. That began an incredible tug-of-war between the two.The crocodile was much stronger

Iifted his legs. And then, with obvious pride,he said to the reporter,"But look at my arms. I have great scars
