There I was, playing Halo 3, waiting for Matchmaking to do it’s stuff, as you do. The teams popped up, and whose was the first name I noticed, directly above mine on the blue team? Blimey, it’s only GRcade moderator The Alchemist “Tiarny” Penguin. I fired off a quick “hi lol” message to him just as the game was starting up, and he sent me a “lol, what are the chances of that?” message afterwards.
We won, despite two of our team leaving, and I notched up a +12, which is always nice. I even took a screenshot of us in action (which was more difficult than it sounds – getting a nice photogenic shot of two players facing the same way without the other team or the background in the way, or everyone’s shields going off in a game of Halo is quite rare).

I took more than that, but I think that was the best one.
