Other mistake: In this episode, they have a leak in the roof. Yet, the house is a two story house with an attic. So it should not be able to leak into the living room. Also, when Carl and Eddie go up to fix the roof, Eddie falls through the roof and ends up on the living room couch. Again, two story house with attic. Should not happen.
Continuity mistake: Towards the beginning, Carl enters with a new video camera and we see a regular view of the scene mixed with POV shots from the camera as Carl narrates. When he's standing at the door with his bag, in the POV shots from the camera you can see that the door is open, but in the wide shots, it is closed.
