Some guy posted a picture of a ghost and a slide and said "guess what this is lol" or something to that effect. The OP's intended answer was "WEE-a-BOO" but Anon being the man that he is, there were some 15 replies in the first two minutes of the thread being made that said "ghost slide."
Then people started replying "where are my subs," "episode 6 was awesome," etc. This somehow managed to mutate into a 150-post discussion on a show which does not exist. Or rather did not exist until tonight, when the space-time continuum ripped open and the collective will of Anonymous made it real.
