Continuity mistake: In this episode, Mort Goldman shows Peter a dating video he made, saying it's how he and his wife met. He is an adult in the video, yet in an earlier episode 'The Kiss Seen Round The World', Mort's wife tells the Griffins that she met him when they were just 14.
Continuity mistake: When Peter goes to see his ex-girlfriend, she says she never washed her hand and takes off her right glove to show a black hand. It is like this right up until Peter leaves. She then turns around and the hands have switched colours.
