In this episode, Marge suspects Bart of destroying a part of the town, so she follows him to get him to confess while Homer bonds with Flanders' dog.
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.
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, which almost causes her to strangle him.
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.
