What is it?
Here is the description for the video above:
Nobody could like Corporal Lawrence. He was a plain man, average height, average build, bland of voice and action. He tended to stare a beat or two longer than was acceptable for people. He rarely slept as well, and bunk mates said he would mumble in his sleep almost constantly. But it all got much worse when the young man fell into a mysterious black hole filled with slime and dirt. This mysterious hole sent Corporal Lawrence into a spiral, forever changing him into menacing SCP-106, now referred to as “The Old Man”.
