2012 August 5, Nathan Rabin, “TV: Review: THE SIMPSONS (CLASSIC): “I Love Lisa” (season 4, episode 15; originally aired 02/11/1993)”[1]:
  Valentine’s Day means different things for different people. For Homer, it means forking over a hundred dollars for a dusty box of chocolates at the Kwik-E-Mart after characteristically forgetting the holiday yet again. For Ned, it’s another opportunity to prove his love for his wife. Most germane to the episode, for Lisa, Valentine’s Day means being the only person in her entire class to give Ralph a Valentine after noticing him looking crestfallen and alone at his desk.
