I discovered a minor glitch with the Anvilrage Taskmasters in Blackrock Mountain. Their leash is broken. They will follow you anywhere in the Eastern Kingdoms, unprovoked.
You do not have to hit them with anything, ever. Just walk up to one and it is stuck with you until it dies. Grab as many as you want. They will gladly kill low-level town guards of your own faction.
It is definitely not intended by Blizzard that this mob follow you around across zones without ever having to hit it even once. I'm not sure what else can be accomplished with them, but perhaps you all can come up with something more exciting. Enjoy.
