FOX has released official The Simpsons Season 37 Episode 14 photos for the milestone 800th episode titled “Irrational Treasure.” Airing Sunday, February 15 (8:00–8:30 PM ET/PT), the special installment delivers a double-story adventure packed with conspiracy chaos, business schemes, and classic Springfield humor.

In the first story, Marge’s crusade to get the family dog in better shape leads her to enter Santa’s Little Helper into competitive canine agility events — ultimately landing the family at the prestigious National Dog Show in Philadelphia. What starts as a wholesome fitness journey quickly spirals into something far bigger, as Marge and Homer suddenly find themselves — along with Santa’s Little Helper — tangled in a historical conspiracy adventure worthy of a National Treasure-style thriller.

The second story shifts focus to Homer, who forms an unlikely friendship with Kirk Van Houten. The pair launch a wildly successful business built around a “crumbless” cracker that sweeps the nation. But when Kirk’s darkest secrets come to light, Homer faces a moral crossroads that could cost him everything — his fortune, his family, and possibly even his freedom.

As the show celebrates its historic 800th episode, “Irrational Treasure” promises big laughs, sharp satire, and over-the-top antics that have kept The Simpsons at the forefront of primetime animation for decades.
