You are probably already infected. If you are reading this and you doubt that you are infected, it is too late. If however you are reading this and have no idea what is going on there is hope yet. NS ghost has risen again to wreak havoc much like Lateralis' comebacks of years past.
To protect yourself from NS ghost you will need a spork.
There are criteria however:
plastic, no metal
attachments are allowed but not encouraged (sporkife, sporkayonet)
keep spork in offhand (non mouse or mousepad hand) at all times until ghost has been subdued by the seal of the 4th sage
That is all.
"Internalize your anger and bottle it up inside and let it slowly seep into your personal life as you self-sabotage all your attempts to be successful and well-adjusted in the marketplace until, years later, you end up beating your wife within an inch of her life in front of the kids at Thanksgiving."
