Everyone knows what a yoyo is right. It is a simple toy. I sphere with a slit down the middle and a string that wraps around the slit. You tie one end of the string on your finger and then you let the yoyo fly. It goes down and then up and then down and then up again and again. Now I have never seen Katherine Heigl go down…………. or up but I can say she seems to be flipping all over the place on Grey’s Anatomy. First she is back, then she is not, then she is angry, then she is not. I wonder if she remembers that before Grey’s Anatomy she was unknown to almost everyone save her parents and a few friends.
