A friend of mine pointed me toward this video that stars a friend of his. See...the circle of life. It's called "Dawn of the Dance!" and it's a whole shitload of zombie hip-hop fun. His buddy is the second zombie in the feature, singing about...zombie vagina.
If you have the time (around 10 minutes) and you are into this kind of thing, well...I guarantee you'll be humming the zombie vagina song later today at some point. It's catchy as all hell.
