Hmm. I seem to remember a classic moment for myself. I was playing Gears of War with a couple of buddies of mine online. We were all on the same team and waiting in the lobby for the other team to arrive. The other team slowly arrives one by one, and the first member of their team to show up in the lobby was an 11-year old. My friend, ElBooner, has this thing where he absolutely has to make fun of the other team for no fucking reason, and the fact that it was someone below 13 was just too easy for him. I guess you could call him the average asshole.
The match starts, and we easily manage to eliminate 3 members of their team. This match was in the bag. As we were looking for the final player on their team, it was much to my surprise to find out that it was the 11-year old. ElBooner bursts into uncontrollable laughter, along with the rest of my team. In the next 3 seconds however...
BOOM
Headshot.
Booner got owned by the guy he had been ripping on the whole match, and I had never seen anything like that ever happen before. But then I, along with the rest of my team gets killed by him as well. I was in shock and awe.
Most hilarious Xbox match I've ever had.
THAT WAS SOME SERIOUS DAVID VERSUS THE GOLIATH SHIT RIGHT THERE.
