Continuity mistake: The bullet holes in Lois keep changing place between shots. This also happens during the flashback in the courtroom.
Continuity mistake: The scene where Lois is on the boat and Stewie is shooting her, the bullets are going through her body and out her back and in some shots you can see exit wounds on her back but in other shots they're missing.
Continuity mistake: Stewie puts the gun and pictures in a bag and throws them in the trash can to get rid of the evidence. When Joe takes the lid off, he just reaches in like Stewie had put them in there separately and not in a bag.
