"Silicon implants" joke
In school one day the teacher decided 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 Ferrari."
The teacher smiled and then called on Little Johnnie.
Little Johnnie stood up and said, "I would want silicon."
The teacher said, "Why Johnnie?"
He responded by saying, "because my mom has two bags of it and you should see all the sports cars outside our house!!"
