Catalog log
Broadcast listing — not a TV Flash recap.
Destined to be yet another classic Halloween-themed episode of THE SIMPSONS, in the opener of the 23rd annual "Treehouse of Horror," we go back to ancient times when a Mayan Homer and Marge are witnesses to the prediction by ancient calendar makers that 2012 will be the end of the world. In "The Greatest Story Ever Holed," the first of three spine-chilling stories, the Springfield Subatomic Supercollider creates a black hole that terrorizes the city, sucking up everything in its path. Then, in "UNnormal Activity" the Simpsons install cameras all over the house when things start to go bump in the night and Marge discovers it may have to do with an unholy pact she made some years prior. In the final thrilling tale, "Bart & Homer's Excellent Adventure," Bart travels to 1974 to buy a comic book at cover price but inadvertently disrupts Homer and Marge's courtship, leading Marge to end up with Artie Ziff .

Why this series still plays
Watch it as a living joke encyclopedia, not a series you owe from pilot to present. The early years still teach how American satire learned to reset weekly; the later catalog is optional weather. You already speak Springfield. This is how the grammar got written.
The first image is a couch, and then it is not. The Simpsons treats the opening gag as a weekly contract: we will reset the living room, and we will still find a new joke about the country that owns it. Fox put a yellow family on Sunday nights in 1989 after the Tracey Ullman shorts, and the half-hour that followed did not merely popularize adult animation. It installed a shared vocabulary. People who stopped watching still speak Springfield.
