Unus Annus, the YouTube channel owned by Markiplier and Crankgameplays, only has 65 days left to live. After that, the channel and all of the videos on it will be deleted forever. With a lifespan of a single year, there isn’t much time to watch all of the Unus Annus that you can! The aim of the channel is to allow Mark and Ethan to experience as many things as possible within the year-long deadline, like a big bucketlist, and some of these experiences are really interesting to watch. Even if you don’t plan on watching any other Unus Annus videos, these 10 are definitely worthwhile.
