YouTube presents a look back at 2012 with "Rewind YouTube Style," a quintessential mashup parody of "Gangnam Style" and "Call Me Maybe" starring the who's who of this year's viral video fame, including PSY, Walk off the Earth, MysteryGuitarMan, Jenna Marbles and more!

Oh look you guys, it's THAT joke again.

This is an actual ad on the side of YouTube. Justin Bieber and Lady GaGa also appear, but the inclusion of Rihanna is rather insensitive, don't you think?

We probably should have tried to hunt down the video, but honestly, the title and screenshot are all you need to know.
