The second time Russ Cargill spreads out the five options on the President's desk, the name bar with 'President Schwarzenegger' on it vanishes and reappears on the desk twice.

When Bart is chained to the post, a large piece of grass used to cover him appears from nowhere.

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.

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.

When Homer circles the dome on the bike, in the first two shots (close-up and wideshot) Homer's left hand is gripping Bart's left wrist, but in all of the following shots it is Homer's right hand that is gripping Bart's left wrist.

During the Green Day concert, the lyric displaying teleprompter sits onstage beside the mic stand, but then disappears, reappears and disappears again by the time the barge sinks.

In the scene where Lisa's boyfriend is trying to play "Lisa's song" from the other side of the glass, at first the guitar has an f-hole, and in the next shot of him, it's a solid body guitar.

When Bart and Lisa are looking at the cabin from a hill, the cabin only has a shallow incline to the water, but in a later shot there's a significant slope.

When Marge is reconstructing Grampa's prophecy with magnets on the fridge, she moves the magnet saying" eyes" up a few inches to complete a sentence. When the shot changes to a wider angle, the magnet is back where it was before she moved it.

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.

At the end when everyone is congratulating Homer, Comic Book Guy is by Homer. Homer then rides down the street to Marge and Comic Book Guy is suddenly by Marge.

When Homer is climbing the dome, there is a shot of the rope. No-one is climbing it, yet a few seconds before people were climbing the rope.
