"Jeff The Killer" has been a 10 year long social experiment involving the injection of human stem cells into a pig's brain. The pig was then given access to forums as well as sites such as YouTube and The Creepypasta Wiki, and rewarded for intaking media related to Jeff The Killer, a fictional character. We hope that you have learned as much from this as we have. Good day.
Any questions you may have will be answered here, to the capacity that I am allowed to.
