Oooh...hang on a second...someone must have put something in my coffee this morning.....
Did I say 9 matches in round 1?

Shouldn't that be 6?
G Vs R, G Vs H, G Vs S, S Vs R, S Vs H, R Vs H....then all the teams would have played each other at least once, which is only 6 matches.
OMG, my maths sucks, doesn't it??
So that's 10 matches a year!! Nothing remotely spooky at all!!
Aw....I really thought that was cool then, too....

Ah well, there ya go.....that's what happens when you have too little sleep and too much coffee, guys....addles your brain....be warned!!
But yeah, Gryffindor would definitely win.
Well, they might have if Harry, Fred, George and Oliver were still on the team. But the new team suck almost as much as my maths, so unless they have some leprechauns smiling over them, I reckon their chances of walking away with the cup for a second year are about as good as my chances of ever understanding quadratic equations....
