end of the world

This kindergartener comes to my class with his thumb all wrapped up in bandages and I ask him what happened. He tells me that he cut OFF his thumb. He was carving a pumpkin--go figure. They were able to take him and the thumb to the emergency room and get it sewed back on and the thumb is fine. Anyway, I asked him what he thought when he saw his thumb lying on the table. He said, " Oh well, end of the world. I have no thumb."
