Year-end mashups are a dime a megadeath, and there are only so many days left in the year to watch them. That's why it's important to know which ones are worth wasting your time on.
When it comes to viral video mashups, the answer is simple, because there really is only one mashup that deserves your ever-diminishing attention span: Videogum's annual Best Viral Videos retrospective-montage (click the link for a full list of videos used).
Think DJ Earworm's United State of Pop but with more nightmare-inducing ice cream commercials and dope grandmas dancing with their grandchildren to "Rack City."
If I had to sum up 2012 based solely on this roundup of the best viral videos I'd say this is the year we finally, mercifully just completely gave up.
