To answer your question with less jocularity, the game will go to the final tribal council when it gets down to 2 or 3 players. The person who wins final immunity essentially chooses who gets voted out last - if it goes to 2 they absolutely choose.
At the final tribal, each player makes a statement, each jury member gets a chance to make a statement or ask questions, and they vote. The votes are read and a winner is selected during the reunion show that airs immediately afterwards.
