- Banned In China: The episode didn't air in Argentina and other Latin American countries (except for Colombia, Mexico, Chile, and Venezuela) because of Lenny and Carl's conversation about Juan Peron making political dissidents "disappear" and mistaking Madonna for his wife, Evita. This was actually Fox's decision and the episode wouldn't air in Argentina until an edited form in 2013 and unedited three years later after the end of Kirchner presidential era.
- Unintentional Period Piece: This episode dates itself during the 2008 presidential campaign, apart from featuring then-famous celebrities like Fred Thompson and Dennis Kucinich. Also, Barack Obama isn't even mentioned in the episode at all, as the episode was likely written before he announced his candidacy.
