Here's the Faceroll Barb vid again for your viewing pleasure.
I started with a Naked Barb, snagged some gear from the AH, total of 20M gold combined with some left-overs that never sold to the AH and other junk in my trunk (stash), pretty convincing how easy this was.
I literally rolled my forehead across my number keys while swinging my mouse around. If I didn't hear myself hitting mobs, I looked up, redirected, and started again.
edit: the last few seconds, I just gave it up because my neck started hurting. I just went and straight HOTA's the E to death.
