Chalk this one up to “Friday Fun.” Lip sync videos are one of the more bizarre segments of the world of YouTube. A regular person stands in front of a camera, usually in a bedroom or basement, and just lip syncs a song. That’s it. Somehow a syncer named Keenan Cahill’s videos have gotten so popular he’s become something of a celebrity for it, and in his most recent video, the rapper 50 Cent appears to sync along to his own verse in a hit single. He doesn’t show up for almost a minute and a half, so you can really get a feel for how odd the video is without him. (And then when he does show up, how odd the video is with him.) Watch the video after the click.
