Postcards from the Wedge

"Postcards from the Wedge" is the fourteenth episode of The Simpsons' twenty-first season. It originally aired on the Fox network in the United States on March 14, 2010. In the episode, Homer and Marge once again try to discipline Bart after Mrs. Krabappel tells them that Bart has not been doing his homework, but Bart has a plan to manipulate Homer's strictness and Marge's sympathetic ear, which backfires when Homer and Marge see through the plan and decide to ignore Bart. These themes had been seeded in the previous season (e.g. "Double, Double, Boy in Trouble", and "The Good, the Sad, and the Drugly"), would culminate in the show's first ever true grounding, and the first to stand for the rest of the episode. It would also be the last episode to feature a grounding, until "The Marge-ian Chronicles" in Season 27, six years later (also written by Brian Kelley).

The episode was written by Brian Kelley and directed by Mark Kirkland. The episode features references to the shows Pokémon, House and The Jetsons. The episode received mostly positive reviews and got an 18-49 Nielsen Rating of 2.6/8.

At school, after Mrs. Krabappel shows a video from 1956 to her students about the future, she tells her students to turn in their homework project (which they had three months to do). Bart did not even attempt to complete his homework, so he tries to make his homework on the fly out of odds and ends found in his desk. Unfortunately, Mrs. Krabappel does not approve, and prepares to send a letter to his parents. She gives it to Martin to mail and he heads out the door. Bart shoots an eraser at the pull station, breaking the glass, pressing the button and activating the alarm. Everyone evacuates, but Bart runs through some 6th graders and gets through them. He almost gets the letter when it drops out of the mail slot, but Groundskeeper Willie heads off with the mailbag.
