Anyone that has followed our great club for any substantial length of time would know that the answer is Carlton.
Sure we have had some great battles with Fitzroy over the years.
Including this one which still rates as one of my favourite games even though we lost - http://www.youtube.com/watch?v=BwDKwa9goOU . I actually got trampled lol.
But back to the subject, Carlton have caused us so much pain throughout the years I find no greater pleasure in just giving it to as many of them as I possibly can on the wayo ut of the ground.
Half of my immediate family barrack for Carlton and half for Collingwood. I remember at one Christmas party one year there was an all-in-brawl when an argument erupted about how Wayne Harmes' ball was actually over the boundary line.
I don't think the two rivalry's compare.
Even though it has quietened down in recent years every Collingwood supporter worth his salt knows that deep down inside all we want to do is beat that ****ing scum and beat them by as much as we possibly can.
Seriously, there are 7000 of our supporters on here from all parts of Australia.
A conservative estimate would say in Round 4 there will be 60-65,000.
Even if it is the only game you go to for the year, get out there and rub it in.
We havent been in a better position in a long time to show that scum that they will never be anywhere near as good as we are.
