You start noticing that people are noticing how you look, and it is a profoundly alienating experience when it first happens, where you go on TV and you say something about some topic of the day, and on the Internet people are like, 'What was up with that shirt?' 'What was up with your hair?' And you think, 'Oh, that's kind of a bummer.'
A mockumentary is supposed to be real, and we were frustrated with mockumentaries on TV, which are so rampant because of the success of 'The Office.' It's not real. You watch and ask why is there even a crew there. They never set it up in the narrative. You have a documentary crew following families for reasons we don't understand.
