Deliberate mistake: During the fire Marge runs back into the house and goes to the kitchen cabinet that has a "keepsake cabinet" nameplate and a keyhole, in order to remove the wedding video, but the nameplate and keyhole didn't exist before. (00:33:35)
Continuity mistake: When "Emperor" Moe appears in front of Marge, after she and the kids return, the two cartridge belts swung over Moe's shoulders switch from his left over the right, to his right over the left. (01:04:50)
EPA official: Sir, I'm afraid you've gone mad with power.
Russ Cargill: Of course I have! Have you ever tried going mad without power? It's boring. No one listens to you.
Answer: It refers to the multi-eyed mutant squirrel that was created by all the pollution in Lake Springfield. Marge probably figured it out, but it was not shown on screen.
