SCP Number: SCP-682-j
SCP Nickname: SUPER BESTEST LIZERD EVER
Ingame mechanics: it would only appear as this document http://www.scp-wiki.net/scp-682-j unless you could somehow implement it into the game physically,
than it would behave like it does in the document

That would be the simplest addition to the game ever. Just a random chance of finding the document

Maybe it spawns in someone's office and there will be another note next to it saying "Dr.<name>, for the last time! Stop making these "joke" documents! The L-0s keep thinking they're real!
