- Near the start of the episode, when Vinny asks Quagmire why he isn't wearing a necklace, when he tilts his head, for a split second, a thin line separates the lighter and darker sections of his fur on his head.
- Near the end of the episode when Peter is apologizing to the family, there is an intersection next to Cleveland's old house that disappears later in the scene. It has also not been present previously.
- When Peter is performing with Quagmire on Conan, Peter rips off his eyebrow but when Peter gets his pick stuck in the guitar, Quagmire's eyebrow returns when the closeup of the guitar is finished.
