    This video is super unclear. Check out the video from TIpping Point Math to get an actual explanation of the theorem. It certainly doesn't help that your 'our proof' pizza is a different pizza than your 'our pizza' and that the labels have all changed. You can try to distract us all you want with the book on the pizza, but we're not learning anything from this video!
