YouTube just released its annual celebration of itself, conveniently mashing up the biggest hits of 2015 into one video. It's basically like a video party for all the YouTubers who were #trending this year, whipping, nae-nae-ing, and being unable to feel their faces. Plus they celebrated the YouTube of yore with bits like The Try Guys doing Rebecca Black's "Friday."

See how many stars you recognize, and follow this list to catch up on what you missed.
