Continuity: During the "back porch" episode, a neighbor is hanging washing on a rope between the houses. The squeaking pulley causes him to walk to the front of the porch to investigate the noise. He then notices a pair of large bloomers come into view against the porch column. In the next shot, there is a distant view of the entire back of that same building. None of the laundry is visible and there was not ample time for the neighbor to remove it.
Revealing mistakes: When Bissonette is opening the can of tomatoes with an ax you can tell that the splash of tomato juice is coming off-screen and not from the can.
