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.

Barely Legal - S5-E8

Connie: You know, Meg, there's no dogs allowed. So, you're going to have to leave. But Brian can stay.
Brian Griffin: You know, Connie, I think I have this theory about why you're such a bitch.
Connie: Excuse me?
Meg Griffin: Brian, let's just go.
Brian Griffin: No, no, no, no, no, no. Hang on a minute, Meg, hang on. You see, Connie, you're popular because you developed early and started giving handjobs when you were twelve. But now you can't stand to look in the mirror because all you see is a whore. So you pick on Meg to avoid the inevitable realization that once your body's used up by age nineteen, you're gonna be a worn out chalky skinned burlap sack that even your own stepdad won't want. How is that? Am I in the ballpark?
[Connie runs off crying].

Trivia: The voices of Brian, Stewie and Peter (as well as other minor characters) are all voiced by the creator, Seth Macfarlane.
