halo 2, the level with the energy pillars holding up that sniper platform in the middle. dude tried to jump up there, took him out with my shotgun. he fell, hit something, landed in one of the pillars getting stuck in his falling animation for a few minutes. one random dude on the other team calls it out, something along the lines of "lol dude looks like he's swimming". everybody gathers in the middle to watch his corpse bob up and down while swimming in the air.
I go around collecting headshots.
