Name eating thingy, SCP-5300... ish. Reclassified a few times as prior efforts were misplaced. You'd swear they were right here. One of them had a good name, something-phage. Borderline antimemetic. Passed back and forth between departments, and never really lost, but not exactly pinned-down to the foundation's typical standards. Rated safe - just kind of a pain in the ass. Mostly harmless.
