The heavily memed "Stupid Sexy Flanders" moment in which Ned Flanders declares that it "feels like I'm wearing nothing at all" is an obscure reference to the once-popular 1970s ad campaign for Underalls undergarments. The commercials were filled with close-ups of women shaking their posteriors, and one concluded with a lady declaring that it "feels like I'm not wearin' nothin'."
This is the first episode in The Simpsons series to be rated TV-14 instead of the usual TV-PG rating.
The title is a play on the title of the Western film Little Big Man (1970), whose star Dustin Hoffman guest-starred in Lisa's Substitute (1991).
This is the second Simpsons episode to be banned in Japan, the first being "Thirty Minutes Over Tokyo". The reason dealt with the Leprosy subplot and the segregation element, as segregation laws were still deemed a sensitive matter in Japan. The episode is also not included on the Japanese version of the Season 11 DVD.
