Nerrazzurri4life is my favorite there. I rarely post there, I haven't posted for months, maybe a year, but whenever I do I reply only to that guy because I know how little it takes to make him lose it and start proving how Inter are angels and we are the evil.
And after he wastes the time to gather "facts" and add links as proves, I never reply back to the subject (and knowing me, You all know that it's not a problem for me at all to enter in such discussions with facts and stats and links

), but I reply with something completely unrelated and he's going mad
