here were a little boy and a little girl arguing on every single subject they can think of by the beach. The little boy kept on looking for a subject that he could make him win arguing since he had not won a single argument yet.

Suddenly he got an idea. He pulled down his short and said:
"Look! I bet you do not have one of these!"

The little girl ran crying to her mother. Not long after, she came back with a smile on her face. She took off her tiny bikini and said:
"My mother says with one of these, I can have as many of yours as I like!"
