So after all these years I still don't know the Janitor's name and supposedly it's part of the box set bonus dvd that contains a quiz with Todd where you get his name if you get enough or all answers right. Is this true?

Regardless, is it something that I still need to just look for when I re-watch it or is it just never mentioned? Another possibility is Glenn Matthews or Tommy from the last episode, but that wouldn't make any sense since Tommy is simply showing you that he's lying about being named Glenn Matthews.
