Wanda Sykes on Education

I was just watching The Ellen Degeneres Show and her guest was Wanda Sykes. Wanda was talking about how she didn't know how to threaten her kids because they are white. Her parents would threaten to knock the "black" off of her. She figured out she can threaten them by saying, "Do you want to go to public school?" She also mentioned that we don't learn a thing in public school compared to other countries. We don't know the metric system at all, besides our doctors. For example if the doctor says there is a tumor in your body that is 9 centimeters, we ask, "Is that bad?" We understand things such as "the tumor is the size of a grapefruit." I found it so interesting  because it is sooo true.
