It's hard to describe...here's what I remember.
The art style is like...it consists of a color and white. (red outline, white filling, red details...etc) and there's a Snake on a skateboard/scooter... and then he gets hit with something, and attacks a cat, and then tells someone about it.
And then a dude has a weird dream sequence where a faceless version of himself takes out his heart from behind a screen...
It sounds really !@#$% up, but hey, it's [adult swim].
But does anyone know what I'm talking about? Can anyone find the video on the interweb?
