The world's greatest fan-fic: Half-Life: Full Life Consequences

If you've ever needed concrete proof that children are, indeed, our future, look no further than Half-Life: Full Life Consequences, an awesome piece of classic fan fiction written by a nine-year-old and then animated by a group of evil geniuses.

By the way, if you need to win an internet argument any time soon, we're willing to bet that "zombie goasts leave this place!" and "BECAUSE YOU ARE A HEADCRAB ZOMBIE" are pretty much going to be the trump card of choice for the foreseeable future.
