New this month Continuity mistake: When Homer and Bart are trying to outrun the crack in the dome, they are falling towards the damaged "P" in the Springfield sign. From their view, the top of the "P" is level with the letters "S" and "R" but when they use the bent leg of the "P" as a ramp to relaunch themselves at the dome, the top of the "P" is scrunched down almost halfway down from the other letters.
Continuity mistake: When Maggie does her disappearing act through the sinkhole, and Marge rushes to get Homer, the wooden porch swing is directly in front of the window, with its top beam as high as the top of the window. When Homer says, "This dome can play tricks on you," note the door and window behind Marge, because the swing is now gone.
Continuity mistake: When a naked Bart is cuffed to the sign post, beyond the grass behind him is concrete walkway then the curb. Then when Homer steps out of the car, the grass goes right up to the curb's edge, but when Bart asks about pants, the walkway is back again between the grass and curb.
