Funniest memory - Day of defeat. One of the spawns on a popular map (Avalanche) has the allies running up a hill from their spawn, past their last flag. There is a small window overlooking this flag, and it was a popular spot for the axis to camp, and kill allies running from spawn. One way to deal with this was to prime a grenade and lob it through the window.
Now, DoD has wave-based spawns, so if you die, you wait for the next wave to respawn. One of my friends (person A) respawned as allies, waited a few seconds to head up the hill and started running. Seeing an axis soldier in the room, person A primed a grenade and was promptly shot by said axis soldier. Another friend (person B) had spawned as part of the next wave, in an advantageous location, and had sprinted up the hill, a second or two after person A. Person B had also primed a grenade. Person B ran over the nade dropped by person A, and died - in turn dropping his grenade. The whole remainder of the team then proceeded to run over this grenade and die.
Net result? 1 person shot by enemy, 9 teamies killed by friendly grenades. Person B was kicked off the server for excessive teamkills.
We were still all laughing about it, days afterwards
