Deliberate mistake: Sport's voice is noticeably dubbed by a different actor in several scenes throughout the episode. Her voice inside Aunt T's house is the original audio track done by the child actor. During the other scenes, the voice is done by June Foray (uncredited).
Continuity mistake: Just before Sport and Jeb come back from their first visit with Aunt T, their parents are walking around the pool deck where it's fairly dry. But when the children come back, the area where they are helped out of the pool is suddenly very wet, probably from earlier takes. (00:13:40)
Continuity mistake: When Sport and Jab jump into the pool for last time, Sport is seen wearing a shirt. But,when she comes out at Aunt T's house she is wearing a swimsuit.
Answer: #4: That he did personally murder at least 14 (Jews). The last word I couldn't quite hear because of the screams, but I hear an "-oz" sound at the end, so it's an educated guess. #5: That he did sign and put into effect specific orders calling for the gassing and cremating of one million human beings.
