I once discovered a bot in Stranglethorn Vale, on the western shore of the lake. I waited for him to engage one of the raptors he was grinding on and taunted it, then kited it to the bottom of the lake. The bot haplessly pursued, but failed to surface for air again

Best part of it? The bot had demonstrated an ability to run back to its corpse when I'd kited it through other mobs and got it killed, but ghosts can walk on water and you have to aim with your mouse to descend below the surface, something this bot clearly could not achieve as he did not rez again after that.

As we were same faction I was able to add him to my friends list and determine he remained online , no doubt floating in ghost form on the lake surface, for quite some time.
