it's true!
http://www.wowpedia.org/Quest:Minx%27ll_Fix_It
this quest is triggered by finding an Illegible Orc Letter as an alliance adventurer in Stonetalon Mountains.
that letter was written by an Overlord of the Horde. he was no peon, so he could for sure buy some ink made of herbs or something. instead: blood and kodo poop<Minx takes the letter from you and begins to read it.>
Uh oh...
<Minx smells the parchment.>
Disgusting!
<Minx folds the paper in half and looks at you.>
The good news is that this isn't toilet paper. The bad news is that the ink on this paper is a mixture of kodo poop and blood. That's not the worst of it, though...
ok, we always knew orcs didn't exactly smell like flowers. but going as far as to use kodo poop as ink is too much.
what's next? devilsaur poop lipstick?
