Continuity mistake: When Karen Black is first shown, her blue uniform is sleeveless, showing her white shirtsleeves. After a cut to the "Dawson's Creek" kids, Peter says "It was a movie in the seventies," and Black's outfit has sleeves.

Factual error: At the end of Peter's trombone solo, he holds out his last note. While holding the note, he moves the slide with no change to the note whatsoever. Since the pitch of the trombone is controlled by the slide, it would be impossible for Peter to move the slide as much as he does without changing the pitch he's playing.
Continuity mistake: When we first see all the guys at the NAAFP meeting, there are two guys in the top right corner; one with a singlet and one with brown hair and a green-brown T-shirt. In the next shot, these two guys come in from the opposite side of the screen. (00:12:15)Blibbetyblip

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 Ulysses S. "Griffin" is chugging beer with Robert E. Lee, Ulysses wins. When he says "How's that Robert E. Lee," he puts the beer glass on his head. After Robert says, "Okay no more slaves, but we still don't have to read books," the glass is in Ulysses' hand. In the next shot it's on his head again. (00:10:05)
