I Love Lisa/References

Trivia

 * Ralph is revealed to be Chief Wiggum's son.
 * At one point, Ralph states that he is going to marry Lisa. Ironically, in "Lisa the Simpson", Lisa fantasises about being married to Ralph

Goofs

 * Up until the presidents play, Lewis is given yellow skin, brown hair and a pink shirt.
 * After Homer says "I'd sell my first-born son", the view switches to a close-up of Bart saying "Hey!", who has suddenly gained a can of Buzz Cola and a thin silver implement in his hands, which were empty in the previous scene. That scene seems to have been copied from another episode where it was part of an eating sequence, the thin silver implement likely being a piece of cutlery.

Cultural references

 * The episode title is an obvious play on I Love Lucy.
 * Ned Flanders serenades Maude with a considerably cleaned-up version of the song "".
 * The candy valentine hearts that have love messages on them are seen in this episode. The only difference is the ones Bart uses were sprayed with messages by him with insults such as U Stink.
