Battlefield 1943 - Playing as a Sniper I was defending a flag (Yes camping) and had set charges across the only bridge, so when the two enemy tanks were half way across BOOM, they fell into the sea mwahahahaha.
Counterstrike - First time playing it LAN, some guy shot me in the back, without really looking i spun around and shot him dead with my machine gun. Not that impressive, no not usually, how about the fact he was shooting out of a window on the higher level of the map and I had a small area to shot at KA POW!
