my irish colleague was explaining yesterday to me how it was certain that australia would beat england, and he was also supremely confident ireland would beat the all blacks, as they're the only team to have consistently done so in recent history. I explained ireland had essentially looked poor to me, and were only through because scotland are even worse. He wasn't a happy bunny. He might be less so now.
I'm almost tempted to put a bet on japan as he forecast them to lose. He also forecast france to lose, but I can't bring myself to bet on them!
