68K Exp? One mob? CATA Rare Spawn Location, Loot, and Screenies- "Madexx"

Kinda funny how Blizz always plays on words....but anyways, whilst farming ore in Uldum, I ran upon this rare cata spawn, took care of business, and what happens upon his/her demise? 68040 non-rested xp. What a nice little bonus, since his/her loot was nothing to be proud of. A grey that vendors for 25g. No epic/blues, not even a greenie. Grey loot. But I guess to look at it, I kinda liked the XP
