YouTube takes a look back at the most popular videos of the year in this tribute video. It features some of YouTube’s biggest stars from 2012, including one of our favorites: Dope Zebra. Fair warning though, watching this DOES mean you have to hear Gangnam Style and Call Me Maybe one more time, but it’s worth it. Check it out and see how many references you recognize. If you actually recognize all of them then your New Year’s resolution for 2013 should probably be “Less YouTube, more books.” Mine is to stop adopting stray cats. Well, actually it’s not so much my resolution as it is a mandate by the state.
