kaelash linked me to some really, really funny videos. I'm so torn as to which ones to link here!
I laughed so much during this one, so even though the video isn't as nice as some of the others, it gets top billing:
The Sands of Uldum has much higher production values and the music is seriously catchy. (Contains a curse, so if listening at work, be sure to use headset. There's a furry joke about 30 seconds in, and though it's marked 'NWS' on the screen, I suspect it's fine... though tasteless.)
Her channel has a ton of videos, I've only listened to a small fraction so far. So very amusing!
