Plot hole: When Dominique is on TV, she says she got the shoes from Al's store. Than the Amish guy comes out to confirm she broke her leg from the shoe he made. Al says yes. She got the shoes way before Al knew he had no more shoes and before they even hired the Amish guy. How can she break her leg from his shoe if he wasn't hired and making them yet?
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.
