Dozens of the year's biggest songs, compiled into one awesome video.

You know, I've always felt that Frank Miller's SIN CITY and Walt Disney's plethora of animated features had a lot in common.

Look people, there are certain things that are just going to get posted while I'm filling in.

I try not to post every little mash-up that comes my way, but I'm secretly obsessed with TV shows' opening credits, so I can't help but be charmed by "The Office" credits re-worked to look like "Dallas" (the original "Dallas," not the crappy-looking TNT continuation of the series).

I don't often like mash-ups, but I can't deny that this one combining "Community" and (500) Days of Summer is done pretty well (video below).

Here's a fake trailer that takes pieces of "Arrested Development" and makes it look like an action movie.

The BP oil spill continues to be super-depressing, so Internet/pop culture geeks showed their support for the cleanup the only way they know how: by expressing themselves through memories of "Saved by the Bell.

Close the door and buckle your sweatpants, nerds, because this is the coolest mash-up I've seen in ages: "Battlestar Galactica" set to the Beastie Boys' "Sabotage," with the scenes cut to mirror the iconic '90s/faux-'70s music video (see the incredible side-by-side video below, via BuzzFeed).

Ordinarily, I wouldn't be interested in a mash-up of a movie that came out six months ago and a TV show that ended almost three years ago, but this video is pretty solid.
