Whose Father is the Tallest?

Three youngsters are having hot discussion, about whose father is the tallest one.

The first one said, "My father is just like statue of Liberty. Your hat will fall off if you look at him"

The second one does not want to loose the discussion. He added, "That's nothing! You can not see my father's hands, when he stands up and waves. They vanish in the clouds".

The third one, a born winner in the discussion, confidently added, "Did your father's hands feel something, when he was waving in the clouds?"

The second one replied confidently that he is going to win the discussion, "Why, certainly, he once told me his hands felt something up in the clouds and he tried to pull that."

The third one said, "That something was my father's under pant. He once complained that they are being pulled by someone while standing."
