AC/DC have come to the rescue of all those bored in their office, re-releasing their "Rock N' Roll Train" as "the world's first music video in an Excel spreadsheet." The video is exactly like the new RS cover boys' initial "Train" video, except this time around singer Brian Johnson is composed of ampersands and asterisks. Plus, the video actually runs through Excel, so it'll look like you're doing work instead of spending company time watching AC/DC videos. We're not entirely sure how they made this video, either some kind of computer program was employed or some guy in his cubicle has entirely too much time on his hands, but it's pretty awesome. Watch a preview of the video here, or download the entire Excel-ready clip here.
