Synopsis by Mark Deming
Bart Simpson (voice of Nancy Cartwright) is used to spending much of his time with his best friend Milhouse (voice of Pamela Hayden), but that begins to change when a new girl moves to town, Samantha Stanky (voice of Kimmy Robertson). Samantha is in the same class as Bart and Milhouse, and it doesn't take long for Milhouse to develop a serious crush on her -- and for Samantha to make clear she's also fond of Milhouse. Bart, who still appears to be stuck in the "girls are yucky" stage, doesn't understand Milhouse's infatuation with Samantha, and when he discovers he's not only brought a girl to their tree house, but is kissing her as well, Bart decides its time to break up this romance before it can spread. Meanwhile, Marge (voice of Julie Kavner) orders a subliminal weight-loss tape in hopes of getting her hubby, Homer (voice of Dan Castellaneta), to drop a few pounds. But Homer receives a "Increase Your Vocabulary" instead, and while he continues to gain weight, when he speaks, he suddenly sounds like a walking thesaurus. "Bart's Friend Falls in Love" first aired on May 7, 1992.
