Corrected entry: When Lisa mocks Bart in French, she sings, "Vous êtes Baby Stinkbreath." However, "Vous êtes" is the formal construction. A person would not use this when speaking to his or her brother, especially when deliberately being disrespectful towards him. "Tu es," the informal form, would be more appropriate
Corrected entry: When Lisa tells Marge about Luke for the first time, Marge says 'I didn't marry the first boy I - Well I did. But you shouldn't." Wrong. Before she had a crush on Homer, she loved Artie Ziff from high school. She didn't marry him, however. Everybody blatantly knows that Marge married Homer, her second crush.
Corrected entry: This is a minor mistake, but why does Luke say he needs help "hanging up these signs" when they have a stake on the end to impale them into the ground? If he had said "put up" then OK, but he said "hang," so this is a mistake because there is no way to hang them up like a hook or something.
Corrected entry: When Sideshow Bob says that he hasn't made any progress on catching the person who is trying to kill Homer, he says, "Go ahead, shock me." and hands Marge the shocking remote. Sideshow Bob has been trying to get the remote ever since he was introduced into the episode. Why, if he has it, does he give it to Marge instead of taking it and trying to kill Bart, which he does at the end of the episode?
Corrected entry: In the beginning, Homer states that he doesn't remember that he was going to be on Taxicab Conversations. By the way Disco Stu was talking, the show was supposed to be a secret from the passengers, so if it's a reality show then they shouldn't have told him.
