I finally unsubscribed from the channel, though, as well as few others. As a result, I don't get that many videos to watch regularly anymore. Regardless, a fair handful still made it to my favorites during 2013.
Conan O'Brien's "review" of Tomb Raider was quite funny.
Also rather entertaining was the hilight reel of the TGS/Co-Optional Podcast episodes. It includes the Jesse's Maid incident I favorited last year.
I liked few music acts as well. Of Eric's many covers, I think his Jurassic Park one was the most to my liking.
The epic rap guy, Dan Bull got some nasty going on in his ears, hindering his ability to continue doing his thing. It hasn't exactly stopped him, though. His Bioshock Infinite rap was pretty cool.
Finally, the title of the best YouTube video of 2013 I give to this Bad Lip Reading of Game of Thrones for the sole merit of making me laugh out loud. Not a completely effortless video either. Totally deserves the views it has got.
