Family Guy (1999)

Road to Germany - S7-E3

Continuity mistake: After getting the uranium, Stewie places it in the time pad and then puts the pad in his jacket pocket. After being confronted by Hitler who promises to spare them if they sing a musical number, Mort interrupts them, and it's seen that he is now standing on the time pad.

When You Wish Upon a Weinstein - S3-E22

Peter Griffin: You better watch who you're calling a child Lois. Because if I'm a child then you know what that makes you? A paedophile, and I'll be damned if I'm gonna stand here and be lectured by a pervert.

Grumpy Old Man - S10-E9

Trivia: One of the cutaway gags is about someone who survived 9/11 because he was late for work watching late night football. Seth MacFarlane missed his flight, which would have been one of the flights to crash into the World Trade Center, because his agent had given him the incorrect departure time. The plane was scheduled to depart at 7:45 AM and his agent had told him it was departing at 8:15 AM. By the time Seth arrived the boarding had been closed and he was told he would have to catch a later flight.

Business Guy - S8-E9

Question: In the episode, Peter threatens to fire Lois, and she responds with "you wouldn't" and Peter then replies with "Oh really, does the name Lacey Chabert mean anything to you?" which in turn makes Lois go wide eyed and reply with "OK, I'll behave" and Peter then goes on to add "Yes you will" Can anyone explain this joke if it is a joke to comprehend?
