You're gonna be uncomfortably energetic!
So the video above, by Thesoultorn, leaves a bit to be desired in the animation department, but in reality it's just a mock advertisement for a World of Warcraft in-game energy drink, Powerthirst. The video gets its jobs done quite well, because I now want to go and grab some Powerthirst.
The video reminds me of the (alcoholic) energy drinks high I had during my powerleveling trip I took when Wrath released. I made plans with The Girlfriend for some rather extended and uninterrupted playtime, and I managed to get to 80 in a few days. Of course to accompany me on my journey I had two cases of Red Bull, a one-seven-five of Grey Goose, and an ample supply of tumblers.
I want more Gnomergy!
Edit: The video is a parody of the original Powerthirst by Picnicface.
