Peeping Mom  "Peeping Mom" is the eighteenth episode of the twenty-sixth season of the American animated sitcom "The Simpsons", and the 570th overall episode of the series. It originally aired on the Fox network in the United States on April 19, 2015. Returning home with Maggie from errands, Marge discovers that a part of Springfield is now totally destroyed, due to an incident involving a bulldozer and a wrecking ball. As Chief Wiggum announces that Bart could be the culprit, Bart says that he wasn't involved at all in the incident. This prompts Marge to follow him everywhere until he confesses. However, Bart seems not to know what Marge is talking about, and is frustrated that Marge keeps following him and being overprotective. Marge eventually is fed up and gives up her plan. Milhouse later meets up with Bart, where it is then revealed that Bart was really the culprit and he plans to create a new incident with the same bulldozer, during the 50th anniversary ceremony of the Springfield Sign. His plan is to knock down all the letters apart from "FIE", in order to create outrage within the residents. However, when he finds some fried chicken Marge cooked for him in his backpack during the ceremony, his conscience eventually wins out. Thinking quickly, he alters the prank so that the letters "F" and "D" remain, as a tribute to the Springfield Fire Department, to a much relieved crowd, and he finally admits his fault to Marge. Wiggum arrests him but allows him to give a hug to Marge. Meanwhile, Homer learns that Flanders got a new female dog named Baz. Though Homer isn't her owner, he eventually bonds with this dog, ignoring Santa's Little Helper. This saddens Flanders and he decides to give the dog to his neighbor, much to his and his sons' chagrin. However, Homer advises him to keep her since he will be a better owner than Homer, who in Baz's eyes is just another dog with whom she can play. The end of this episode shows us Santa's Little Helper and Baz preparing to fight in a Far West style. The episode received a 1.4 rating and was watched by a total of 3.23 million people. Dennis Perkins of "The A.V. Club" gave the episode a B-, stating "Peeping Mom’, unfortunately, shows what happens when the show dips back into the well without adequate reason...’Peeping Mom’ just doesn't go deep enough to be anything but an example of latter-day, scattershot Simpsons."
