I'm a little puzzled by Doug's insistence on using 'brick jokes' in every episode so far, especially as they mean every episode begins with a scene that seems unfunny and unrewarding, even when it eventually pays off later in the episode. Doing it once or twice is okay but it seems like these 'brick jokes' are going to become this series particular recurring trope. Strange that Doug who felt strongly about the need to move away from 'monster of the week' formula to stop the show becoming predictable seems to have decided to use a recurring trope throughout this series on the basis of the first three episodes. I like brick jokes when done well, as the Swedish moose joke was, but the payoffs in the other two episodes have been weaker, even though they did produce some wonderful facial reactions from Rimmer in Lemons. I actually now feel conditioned to watch the next episode expecting an unfunny opening sequence with a bit of seemingly abstract dialogue that will come back later in the show. I've been trying to think about whether Red Dwarf has done this kind of joke before, I'm sure it has, but I'm struggling to think of examples.
