Lisa the Simpson/References

Cultural references

 * When Lisa is figuring out the puzzle, one of the clues she rules out is that it's not one of Prince's names, a reference to the period between 1993 and 2000 that Prince changed his name to a symbol and was known as "The Artist Formerly Known As Prince" (or simply "The Artist").
 * Lisa's story is similar to the book, , where a man writes in a journal about his slide into mental retardation (the season 12 episode "HOMЯ" would follow a similar plot that Flowers For Algernon does).
 * Jasper's subplot calls to mind the festival, held annually in Nederland, Colorado. The events of this festival are in homage to Grandpa Bredo, a cryogenically-frozen corpse who, since 1989, has remained in stasis inside a Tuff Shed and inspired two documentaries. It is unknown whether this festival inspired the scenario.
 * The TV show When Buildings Collapse is a parody of the Fox special When Animals Attack!.
 * The music playing in the background while the buildings collapse is 's .
 * The Leaning Tower of Pizza Restaurant is a pun on the Leaning Tower of Pisa.
 * The House of Usher is a reference to the Edgar Allan Poe short story "". It resembles the abbey in Italy prior to its being bombed by the United States during World War II.
 * Lisa recommends some books to TV viewers: ', by ; ', by ; and , by ("possibly the best book ever written on the subject of turtle stacking", according to Lisa, and to which Chief Wiggum heartily agrees).
 * Lisa creates a small pig from a rubber eraser and push-pins, which was featured in a Life in Hell comic strip.
 * The filmstrip title "Someone's in the Kitchen with D.N.A." is a reference to the song "".

Goofs

 * Before Grampa tells Marge how to cut his hair, Marge uses the scissors to try and cut Grampa's hair, but she actually doesn't cut any.
 * After Lisa's speech, Kent Brockman is colored differently.

Continuity

 * Jasper is also seen frozen in the Kwik-E-Mart freezer in the comic story Kwik-E-Mart Holiday Savings Circular. In the story, just as in this episode, Apu attempts to exploit Jasper's situation for financial gain.
 * The scene where Lisa imagines herself as a morbidly obese redneck is similar to Bart's fantasy of him being a lardo on a workman's comp in King-Size Homer. In the fantasy Lisa wears Homer's Muumuu and in both fantasies Bart and Lisa have southern accents.
