Rule 5 states that mmateri is always wrong. Any argument you have with him will end in him being wrong. mmateri being the village idiot on thisaintnews.com, has been proven wrong in every argument he's been in, especially when he uses his "facts"."
matteri: Canada has the biggest army in the world.

Anyone with sense: I'll just skip the 2 hours of proving you wrong and call Rule 5 early.
