Lisa is put on anti-depressants after reading Internet reports that Springfield will be a barren wasteland in 50 years. Meanwhile, Bart and Milhouse's friendship is, once again, strained, thanks to a girl named Jenny.

!! Tropes:

* BaitAndSwitch: At the end, Bart is seen offering someone flowers and asking for forgiveness. He was talking to Milhouse.
* HopeSpot: After Bart reveals to Jenny about the lies, it looks like she is going to forgive Bart as she smiles...only to frown and dump Bart.
* HumiliationConga: In additional to being exposed as the "Ay, Carumba" kid by Milhouse before Jenny, Bart is seen crying back home after she dumps him.
* MushroomSamba: Lisa starts seeing smiley faces everywhere once she's on the pills. It reaches the point where Marge catches Lisa almost ready to make out with an electric fan.
* PaperThinDisguise: Homer suspects ''Milhouse'' is "El Barto".
