Springfield Connection - S6-E23
Other mistake: Right before Homer draws a line between him and Marge in their bedroom, there is a weird glitch where the scene fades out a bit and back in. It almost looks like a power outage but serves no purpose. This is on the Disney+ version of the episode.

Suggested correction: It seems like it was done on purpose, as it includes the sound effect of a light bulb burning out. Clearly, it was meant to reference Hans Moleman's electric chair scene. The electric shock probably used up too much power—that's the joke.

Deliberate mistake: Lou and Eddie are driving Bart around in the cop car. Bart asks when they're going to shoot people. The shot cuts to Lou, who is driving. The entire frame of the car disappears around him and it's just him superimposed over a background. The shot cuts again and the frame is now visible. Even if it was a low-angle shot, you'd still see the roof of the car.
