As TV Tropes would say, that image Crosses The Line Twice! It's disturbing, but funny at the same time.....

.....that image is Suicide Mouse In Name Only though, having as much to do with the creepypasta as this. In the pasta itself and in most recreations, Mickey doesn't even kill himself, the title coming from what the psychological effect of the video in the story does to people. The exception is the video you linked, and even then it is debatable whether Mickey killed himself or he collapsed and died due to the demonic figure in the end.

.....it's 2:45 AM. Why am I still awake?
