In the episode of the Simpsons when Homer gets his jaw wired shut he is rehearsing a play with Bart about 16 minutes into the episode. They show Bart standing next to a couch, and there is a doorway behind Marge showing the same exact room with the same exact couch. Did the Simpsons add an extra room with the same furniture?
Sigh... the Simpson’s have to rooms and in both these rooms there is the same identical couch. One room has the TV, backdoor, etc. The other has the book case with the entrance to the hallway. Now... I’m not sure if you forgotten this or if you haven't realized it yet.
