Robot Unicorn Meme
At first, it was just an innocent game, but now it's gone viral and you won't be able to get it out of your head. Robot Unicorn Attack is an addictive little Flash game on the Adult Swim site. It was cloned from a better game called Canabalt, but pumped up with enough unicorns and rainbows that you'll think you're on acid.

By itself, that wouldn't be enough to turn it into a meme, but here's where it gets really good: the Erasure song in the background of the game, "Always," is one of the catchiest earworms you've ever heard. Even if you hate it at first, you won't be able to stop thinking about this song.

Sing it with me, now:
I wanna be with you
And make believe with you
And live in harmony harmony oh love
They're having a field day with this song on 4chan's videogame-themed image board, /v/, and related websites, posting a bunch of Rageguy-like drawings of people getting angry at Robot Unicorn Attack and then getting sucked into an Always-induced happy trance. Instead of shouting FFFFFFFFFUUUUUUUUU!, now we're all living in harmony, harmony, oh love!

Here's the original "Always" video, by Erasure:

And here are some of the images fueling this emerging meme:

You might not be able to stand "Always," at first, but it sure grows on you:
