Lisa discovers a group of Wiccans who are accused of making the town go blind. Meanwhile, Cletus the Slack-Jawed Yokel and Homer make moonshine.

!! Tropes:

* GothGirlsKnowMagic: Invoked and subverted. When the three wicca teen girls Lisa befriends are arrested, suddenly, half the town becomes blind and the girls are blamed. Turn out that they are innocent and the cause of blindness was not the magic.
* OverlyLongGag: Bonk It! Twist It! Smack It! Thwack It!
* StrangeMindsThinkAlike: To get rid of the Bonk It noise, Homer threw the game away from the car. Thanks to a man at a nearby car having a similar idea, the Simpson kids got a new Bonk It soon after.
* TooDumbToLive: Chief Wiggum pointing his gun at a fly that landed on his nose.
* TheWeirdSisters: Lisa gets lost in the forest and runs into three teenage girls who are performing a UsefulNotes/{{Wicca}} ritual. The way the three are first seen--three cowled figures around a cauldron--alludes to the witches of ''Macbeth''. Eventually the three invite Lisa to be the fourth member of their "coven", but the induction is not complete when Chief Wiggum arrests the girls for witchcraft.
* WitchHunt: Of the drowning kind of hunt.
