This final episode of Season 3 includes a nice scene showing Rob and Laura pasting green stamps into booklets.
Laura: “If you want to end up another Dwight Heatherton, go ahead!”
Rob: “Who’s that?”
Laura: “Dwight Heatherton happens to be an excellent writer who is unknown because he gets no publicity.”
Rob: “Well how do you know him?”
Laura: "Oh Rob, he's famous!"
