Continuity mistake: When Brian and Stewie arrive in Leonardo's atelier, we know that they are in Florence for two reasons: because of history and because we see Palazzo Vecchio (which is in Piazza della Signoria, in Florence) outside the window.

And Then There Were Fewer - S9-E1
Continuity mistake: There are several differences during the flashbacks and what actually happened. Such as when Muriel is killed Diane appears with everyone else, but in the flashback she appeared moments later. Second, when everyone appears in front of Derek's dead body there are two differences, Tom doesn't say "Dear God!" in the flashback and Diane appears 1 second later in the flashback. Third, Stephanie doesn't say "Did the cork hit me?" when she is shot in the flashback. Fourth, Priscilla isn't wearing a scarf in the flashback even though when it actually happened she was wearing a scarf. Fifth, when Derek says he is going up to the roof he is standing next to Peter and Lois, in the flashback he standing next to Lois and Jillian. Sixth, when Derek leaves the dining room to go to the balcony, no-one is standing next to the door, but in the flashback Diane and Doctor Hartman are standing right next too the door. Seven, when Muriel is killed she is in the middle of a hallway. But in the flashback, she is killed outside Tom Tucker's room.
Continuity mistake: When Bertram sneaks into Stewie's bedroom, he tiptoes past Stewie, who is sleeping. But in the next close-up of Bertram, the shot pulls back and pans the room so we see Stewie's crib is empty. But in the next shot, Stewie is still sleeping, and then he wakes up. (00:10:25)
Continuity mistake: When Bertram climbs through the window into Stewie's bedroom, just as he tiptoes past a sleeping Stewie, the lightswitch on the wall is in the up position and the room is dark, but two shots later Stewie wakes up and now the lightswitch is in the down position so Stewie flips it up, then the light turns on.

Continuity mistake: During the AA meetings, Dr. Hartman's, Bruce's, and Tom's buttons switch sides between shots.
Continuity mistake: The buttons on Chris' and Peter's suits switch sides while they're at church. Also, when Lois goes to see Joyce after the news anchor's exposé, both women's buttons are a problem when the buttons do not change sides in the mirror's reflection. (00:04:00 - 00:13:30)
Continuity mistake: After Joyce reveals the secret on the news it soon cuts to Joyce sitting in front of the mirror at Quahog 5, and in the mirror's reflection we see the door behind Joyce opens at the real Lois' right side (blocking the lightswitch), but in the next shot facing Lois the door opens the opposite way (not blocking the lightswitch). (00:13:25)
