I knew I had him in the first round. Almighty God was with me. I want everybody to bear witness. I am the greatest! I'm the greatest thing that ever lived. I don't have a mark on my face, and I upset Sonny Liston, and I just turned twenty-two years old. I must be the greatest. I showed the world. I talk to God everyday. I know the real God. I shook up the world. I'm the king of the world. You must listen to me. I am the greatest! I can't be beat!
