Shhhhhhh. Bite your tongue. Zip it.
If you see a bloke in a Maroons jersey don't make that predictable joke about how Sydney's average IQ is halved when the visiting supporters get off the plane. Don't stick another pin in your Cameron Smith voodoo doll. Don't even say the words Johnathan or Thurston out loud!
Don't boo and jeer when the Maroons run out on Wednesday night. In fact, just to keep the noise down, take your shoes off before entering ANZ Stadium and tip-toe in.
For the past few days we had been worried about the eerily quiet build-up to Origin 1. I even foolishly rebuked coaches Laurie Daley and Kevin Walters for being too nice and not fuelling the usual Phoney War with the regulation sleights, insults and petty mind games.
But now, on game eve, the sound of Origin silence seems golden. At least for those hoping NSW can somehow win and avoid what would then be an inevitable straight sets loss in Brisbane.
Defeatist? Yes. But if the definition of insanity is doing the same thing over and over again and expecting a different result, surely anyone who picks the Blues to win Origin after nine defeats in 10 years shouldn't be allowed to use the grown-up scissors.
