You might recall from back in October of last year when footage of DARPA's PETMAN, the headless humanoid robot from Boston Dynamics, was released. The Internet kept cracking jokes about infusing the video with the immortal Bee Gees classic, "Stayin' Alive." Some even attempted said fusion to middling success. As it turns out, folks had been seeing the same funky beat in the robot's movements for years. But now, thanks to YouTube user timtrusler, we finally have a definitive version of PETMAN with true swagger. Even robots can stay alive with the best of them, though they don't take kindly to being pushed.
