Here are a couple of moments that happened to me. I chose these because these are the only ones I can remember.

I'm playin Wake Island, and someone kills me at North Base. Then 3 seconds later, it says I killed another guy at Airfield. I wasn't anywhere near the guy who died. So the guy I "killed" asks, "Where were you?" Then I said, "At North Base... and I died before you got killed..." The other guy then says, "Good shot." I laughed so hard then. It may have been funnier if you were there...
Anyway, this is an even better moment.
Once again, I am playing Wake Island. We are playing Raver's building mod and I came up with the idea to "party" on the roof top of the big white building in airfield. So me and 2 other guys parachute onto the roof and start sniping. We are all prone. Then I start pushing Darkraver by crawling into him. Eventually I manage to push him off the edge. Before he hits the ground he lets out parachute and survives. I am laughing so hard as I move backward a bit. Then, to get revenge on me, Dark throws a grenade up there. Instead of killing me, it kills the other guy that was up there. I practicallly fell out of my chair when that happened.
