Continuity mistake: In this episode, Al has taken on the persona of Axel Bundy, a rock star, so he can fly first class with older rock stars. But before they start a jam in the first class lounge pre-flight, one of them calls him AL when he's prodding Al to join the group when all they knew him by was the name Axel.
Continuity mistake: Marcy's niece asks Bud to take a shower so she can get out of her sticky clothes. Next scene, she's sitting on the couch with a towel on her head. She talks to Bud awhile then gets up and leaves. Shes wearing the same "sticky" clothes and she takes the towel off her head, and her hair is completely dry.
Other mistake: Peg reads from a headline saying "[Marcy] announces NBC fall schedule people still disappointed." But the text below it reads "State officials..." What would state officials have to do with that? Also when you see each headline the article is the same for each one.
