Revealing mistake: Death's right foot disappears when he gets up after he says "You know, my ankle is starting to feel better." (00:21:15)
Continuity mistake: When Peter enters the cockpit and accidentally kills the pilots the cockpit looks small enough so that it could only fit Peter and the pilots in their seats. However, when he turns around to leave the cockpit looks big enough to fit an entire group of people.
Continuity mistake: When Karen Black is first shown, her blue uniform is sleeveless, showing her white shirtsleeves. After a cut to the "Dawson's Creek" kids, Peter says "It was a movie in the seventies," and Black's outfit has sleeves. Later, when she is helping people off the plane, her uniform once again is sleeveless.
Continuity mistake: When Peter is on the phone talking to Death the color of the napkin on the table changes from red to a brownish color.
Continuity mistake: When Death is talking about how he wanted to be a wood nymph, he has no pillows, but in the next shot, he has a blue pillow.
Continuity mistake: When Stewie shoots the darts at Lois through the straw they get stuck to the cupboard door but in the next shot they are gone.
Plot hole: As evidenced by the big bar room shootout, even if they couldn't die in this episode, wounds would still show up on your body (if shot with a gun, there would still be a hole). So, when Peter jumped off the building, when he hit the ground he should have been reduced to a fleshy puddle, even if he weren't dead.
Continuity mistake: During the yard sale, Lois goes outside the house but she doesn't close the door. She talks to Peter and the shot later, the door is closed.
Other mistake: Throughout many episodes, it's discovered that anybody that touches Death immediately dies. When Stewie learns that Death has come for Peter, he immediately touches his finger to lead him inside but manages to live.
Continuity mistake: Death has the TV remote asking how old the TV is. As Lois talks, he puts it down, then it suddenly disappears altogether.
Continuity mistake: As Quagmire and Cleveland are talking to Peter, the hat Cleveland is wearing disappears and reappears between cuts.
Revealing mistake: While Lois is unbuttoning her shirt, Death's feet and legs aren't visible on the couch, even though he is lying on it.
Continuity mistake: When Lois is handing out everyone's lines for the play, Meg doesn't have glasses on. Split second later they appear. (00:09:47)
Continuity mistake: When Diane Simmons is announcing that she will play Anna, the five little pictures behind her change between shots. (00:11:15)
Continuity mistake: During the end of Peter's "revised" version of "The King and I" right after the scene where Brian and Peter kung-fu fight, the scene transitions to the next scene where a bunch of girls with bikinis on are surrounding Peter. During the transition, a girl appears out of nowhere. She is blonde and is leaning on Peter. (00:19:10)
Continuity mistake: When Peter shows Lois the newspaper about the play the headline "Long live this King" is in black text. In the next shot when he puts the paper on the bed, the headline has changed to red text. (00:21:10)
Other mistake: In the scene where Einstein is stealing Smith's theory, when Einstein pulls the metal bars down, they should land on Smith's head, but Smith inexplicably moves forward and the bars land on his back.
Continuity mistake: Lois is wearing a green dress when peter is looking at her from the stage, but she's wearing a blue dress throughout the scene.
Continuity mistake: After the "Lint" scene, Meg's glasses disappear.
Revealing mistake: Einstein's eyes briefly pop out of his head during the Theory of Relativity scene.
Answer: Lacey Chabert was the actress who originally voiced Meg in early episodes. She left of her own accord due to being in school and other acting work; Seth MacFarlane has stated there was no tension with her leaving, but it makes for a handy joke for the show.
