We're unsure what drove this employee to a meltdown worthy of Office Space, but we are sure his co-workers didn't feel it justified having their cubicles destroyed. About halfway through the video the man has picked up what looks to be a lamp and is smashing it against the walls, when one brave co-worker deftly grabs the lamp and flings the rampaging employee to the ground. Alas, the destructive worker gets up unfazed and continues his reign of destruction.
There's simply too much to in this video to describe, so you should just watch it for yourself:
Someone, most likely a security guard, eventually tased the man to end the situation.
