Corrected entry: When Peter goes back in time to when he was eighteen, Brian points out Lois and refers to her as "eighteen-year-old" Lois. In the episode "Let's Go To The Hop", in the second season, Lois mentioned that she is two years younger than Peter. She would actually be sixteen when he is eighteen.
Corrected entry: In the episode "No Chris Left Behind," when Peter and Lois are talking about Chris in the kitchen, Peter spots the chicken and then the chicken crashes through the window. After a few shots of fighting, they then both crash through the same window, but the break in the window from the chicken is missing.
Corrected entry: When Peter and Kyle are talking in Kyle's bedroom (just before Peter beats Kyle up), Kyle mocks Peter by saying "My name's Peter Griffin! I'm a big fat dumb butt-face!", but Peter never introduced himself as 'Peter Griffin', he introduced himself as 'Chris Griffin's father'.Blibbetyblip
