Continuity mistake: When Marge and Homer are watching the news about the silo being found, the '6' on Kent Brockman's microphone keeps getting smaller, the color of his belt buckle changes and the landscape in the background changes. (00:32:00)
Continuity mistake: When the angry mob breaks down the front door of the house, the door knob is on the right side of the fallen door, at Chief Wiggum's feet. However, when Maggie breaks her bottle and thrusts it forward, in the next shot as Mr. Teeny turns and runs away, the doorknob is on the left side of the door, at Bumblebee Man's feet. (00:32:20)
Continuity mistake: After Homer and Marge watch the news about the silo found in the lake, when Homer walks to the window we see that there are two blue panel drapes with tiebacks on the left and right side of the sliding window. However, when Homer shouts at the mob in the exterior shot, there is also another blue panel hanging down at the center of the sliding window, and the side panels are hanging straight down, without the two tiebacks. (00:32:30)
Continuity mistake: After the news broadcast about the silo being discovered in the lake, in the first shot of Homer nailing the bedroom door shut, the blue panel drapes and valance have become beige (seen right behind Lisa and Bart). (00:32:30)
Continuity mistake: When the mob are invading, Lisa sees Colin in the crowd with a bouquet of flowers and nothing else. Later on after the house is destroyed, he suddenly has a guitar with him despite not having it with him a few minutes earlier. (00:32:30)
Continuity mistake: During the scene with the angry mob, knobs on the bedroom's wall cabinets keep switching between being on the left or right sides of the cabinet doors (which would also change the direction those doors open). (00:32:50)
Continuity mistake: When the mob approaches Homer's house, it is undamaged. However, a few seconds later when everyone is out of the house, it is suddenly ablaze, and it is clear that it's falling apart. But when the sink hole sucks the house in a few minutes later it is undamaged, and no evidence of a fire is visible. (00:32:50)
Continuity mistake: When Bart looks out the bedroom window, and Ned tells Bart that he and his family should crawl out on the plank to his house, the pair of blue panel drapes and tiebacks have turned yellow. (00:33:00)
Continuity mistake: After Homer nailed the bedroom door shut and then mimicked the sound of a chainsaw, when the hands of the angry mob push through the holes again, we see Marge and Lisa sitting at the edge of the bed where the bed's tall footboard should be. The footboard is back when Spider Pig pushes the plank off the windowsill. (00:33:05)
Continuity mistake: When the mob is charging toward the Simpson's house, we see Nelson in his regular clothes. When he shoots the arrow at the Simpson's, he is wearing a Springfield T-shirt. (00:33:15)
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 Marge runs back to the kitchen to retrieve the wedding video, the house is ablaze. In the next shot, when the mob is carrying the car away, there are no flames visible in the house. (00:33:40)
Continuity mistake: When the Simpsons are trying to escape the angry mob, as Marge and Homer get into the car, the driver's side mirror is missing from the door. Then in the next shot, the side mirror appears on the door, but now the rear-view mirror has vanished. (00:33:40)
Continuity mistake: While the Simpsons are walking the plank of wood between their house and Flanders' house, in the shot right after Plopper the pig pushes the wood plank off the windowsill, just as the Simpsons fall and the arrows fly by overhead, note the mysterious cable box and long cable that have suddenly appeared out of nowhere, attached to the wall beside the second window on the opposite side of the chimney. (00:33:50)
Continuity mistake: When the angry mob is outside the Simpsons' home, Lisa sees Colin in the crowd. Carl is next to him, with his torch in his left hand. In the next shot, when Carl sets fire to a bouquet Colin brought for Lisa, Carl's torch is now in his right hand. (00:33:55)
Other mistake: For the car to be carried by the angry Springfieldians, there would need to be a big jump between the ground and the car, but from the car view there is no sign of that. (00:34:00)
Continuity mistake: When the Simpsons see the nooses in their backyard, you see Jimbo and Kearney put a pacifier on Maggie's noose, but in the next shot where you can see the nooses, the pacifier is gone. (00:34:15)
Continuity mistake: When Nelson says "I'm using a red arrow so I know who I kill," the word "Springfield" appears on his sweatshirt. It wasn't in the previous shot. (00:34:40)
Continuity mistake: The arrow that Nelson fires into Homer's head changes place between shots. It goes from on top to the side. (00:35:30)
Answer: The family doesn't treat him very well, particularly Homer. He may have wanted some revenge on them. Grampa is also a little senile.
