Tolkien, Linda and Steve's son came home and Linda asked:

Linda: "Hey, Tolkien. How was school?"

Tolkien: "Mom, Dad. Why do we have bigger houses than everyone else?"

Steve: "Well.. Son, we went to college and your mother is a chemist for a pharmaceutical company and we make more money than others. But your friend Eric Cartman's mom is a crackin' whore"

(HELP- I WAS DYING WHEN STEVE SAID THAT-)
