Let me begin by saying that, despite having been aware of the whole Rebecca Black media blitz that’s occurred over the past two weeks, I had yet to experience the hypnotic badness of Black’s debut single, “Friday,” until a few days ago when my curiosity got the best of me. I won’t get into how terrible the song is, because you can find much wittier commentary on the subject somewhere else on the Web, but I’m really glad that I finally caved in, or I wouldn’t have been able to enjoy the sheer awesomeness of Stephen Colbert’s performance of the song on last night’s episode of “Late Night with Jimmy Fallon.” Check out the video below, and be sure to watch the whole thing so you don’t miss any of the cameos or Auto-Tune fun.
