If you surf YouTube as often as we do, this video is going to blow your mind. The site has referenced just about every popular Internet sensation and meme imaginable from the year in its YouTube Rewind: Turn Down For 2014 [1] video, and it's basically an online masterpiece. We're talking Jenna Marbles, Bethany Mota, Tyler Oakley [2], Michelle Phan [3], and tons more stars dancing their way through the epic hit. Even late-night show hosts John Oliver, Stephen Colbert [4], and Conan O'Brien [5] make appearances. Oh, and make sure you watch until the end for some major hamster cuteness.
