[Portal] The Defective Turret Song

i don't own anything in this video, as it was made by vampiremeerkat on deviantart. original video can be found here: http://fav.me/d6jzj5t i only uploaded it to youtube because the version i found on here was messed up and off-sync, and i thought a better version should be uploaded. not only that but the uploader didnt credit the original creator.
