Brother from Another Series
My Sister, My Sitter
Homer vs. the Eighteenth Amendment


  • Bart mentions that he is "two years and thirty-eight days" older than Lisa. Bart's birthday falls on April 1st, so this would make Lisa's birthday May 9th (even though "Lisa's First Word" implies that Lisa was born around the time of the 1984 Summer Olympics).
  • When Rod and Todd are being chased by a moth, they both have Entomophobia.
  • When Lisa talks to Mr.Smithers at the Hospital, everyone in the queue is seated, only Mr.Smithers is standing and ashamed, for a very peculiar reason.

    • Unusual sex practice
