Picture the scene . . .
Wayne Barnes: "Siya, I need to speak to you."
Siya Kolisi: "Sure ref, what's up?"
WB: "Just to inform you that the yellow card given to Sam Cane has been upgraded to a red card, He won't be returning to the field."
SK: "Ummmm . . . okay, thanks"
WB: "Hang on, that's not all."
SK: "Yes?"
WB: "It also means you now have to win the game by 10 points otherwise New Zealand are the winners."
SK: "What?"
WB: "It's the new Mozart Law. Comes from the very top. If a player is red carded it intiates the handicap system. You now need to win by 10 points or more or else you lose."
SK? "What? Why do we get punished by 10 points because they got a red card?"
WB: "Don't blame me, like I say it's the new Mozart Law."
