The average online-savvy person probably watches a ton of YouTube videos over the course of a year—and memes come and go so fast, it's kind of hard to keep track of everything that was popular in 2013. Thankfully, this YouTube Spotlight video that features a ton of cameos of the most viral stuff this year should be a good refresher.

It's kind of amazing that they managed to cram so much into five minutes, eh? Got any videos featured here that you particularly loved or hated? I mostly felt baffled that all this stuff happened in 2013, to be honest.

And make sure to check out the most-watched gaming YouTube videos, too. They're great.
