Lois: Hello?
Peter: I can't take the trash out today, I'm working late at the office.
Lois: The caller ID says you're calling from the kitchen. In fact I can see you.
Peter: [Edging sideways.] OK, can you see me now?
Lois: No.
Peter: Now I am at the office.

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?
