I agree. I don't really want him to have a name, unless it is the most rocking name ever. I wouldn't mind if the janitor's name was Neil Flynn, but most people except that by now. And his name better not be Josh like in that tad bit of dialogue in the seventh season. Maybe his name will be Brown Haired Janitor so he can end up with blond-haired doctor

That would be cute, but it's totally not happening.
