This will never stop being funny.
(It's WoW humor, and it helps if you're familiar with Ulduar. If not, it might be good to know that
there is a part of Ulduar where there is an unpassable ravine ... that conveniently has a boss, Kologarn, standing/floating/wtfever in the ravine, and when your group kills Kolo, he conveniently dies in such a way that he forms a bridge into the next part of Ulduar. ...of course, you could probably guess that from context anyway, but it's fun to over-explain jokes!
