In this episode, we get a better look into Luke's apartment. Though it is a bachelor pad, it still has that country, rustic feel from the days when it used to be his dad's office.
For example, this card catalog, a bigger model of the one downstairs in the diner, would totally be back in style these days.
I also love Luke's ingenuity in using objects for other purposes than they were intended for. Here, he uses an old safe as a side table.
