In school one day the teacher decided that in science class she
would teach about materials. So she stood in the front of the class and said,

�Children, if you could have one raw material in the world what
would it be?�

Little Richie raised his hand and said �I would want gold, because
gold is worth a lot of money and I could buy a Porsche.�

The teacher nodded and called on little Susie. Little Susie said �I
would want platinum because platinum is worth more than gold and I could
buy a Corvette.�

The teacher smiled and then called on Little Johnny. Little Johnny
stood up and said, �I would want silicon.�

The teacher said, �Why Johnny?�

He responded by saying, �because my mom has two bags of it and you
should see all the sports cars outside our house!!�
