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. (00:10:20)

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.

Continuity mistake: While Lois is in the Paris hotel suite packing her suitcase there are two doors behind her, and Bonnie opens one of those doors.
