Milhouse of Sand and Fog

"Milhouse of Sand and Fog" is the third episode of the seventeenth season of the American animated television series The Simpsons. It originally aired on Fox network in the United States on September 25, 2005.

Plot
During Reverend Lovejoy's sermon, Maggie is scratching. The family takes Maggie to see Dr. Hibbert, who diagnoses Maggie with chicken pox. Inspired by Ned Flanders' suggestion of purposely exposing his sons to chicken pox, Homer invites all the neighborhood kids over to the Simpson house for a "pox party". He ends up catching it himself, by drinking from Maggie's milk bottle, having no childhood immunity. Milhouse's parents Luann and Kirk attend the party, and after getting drunk on Marge's custom Margaritas, they resume their relationship.

Milhouse feels neglected because his parents are not fawning over him as they did while they were separated. He schemes to break them up again, and Bart helps him with a plot borrowed from The O.C.. The boys place a bra, belonging to Marge, on Kirk's bed. Luann finds the bra, assumes Marge is having an affair with Kirk, and informs Homer. When Homer confronts Marge, she angrily denies the allegation and kicks him out of the house.

Prodded by Lisa, Bart confesses to Marge that he left the bra in Kirk's bed, but Marge refuses to reconcile with Homer as he still does not trust her. In order to bring Homer and Marge back together, Lisa inadvertently influences Bart and Milhouse to plan to throw a dummy that looks like Bart off a cliff into the river below, while Homer and Marge, after receiving false messages from each other to meet, watch. However, after breaking his glasses, Milhouse accidentally pushes the real Bart off the cliff. Homer jumps into the rapids to save him, but they end up clinging to a rock near a waterfall. There, Bart confesses to Homer what he did, leading Homer to strangle him. Marge advises them to trust her and let go of the rock. They let go, and she catches them while swinging from a rope tied to a tree. Once safely on the riverbank, Marge and Homer reconcile. They see Milhouse, thinking Bart died, jump off the cliff, leaving his fate unresolved. Marge wonders if Milhouse can swim, to which Bart asks "What do you think?"

Production
Writer Patric M. Verrone based the episode on his own experiences at the time since he was raising three children and dealing with chickenpox.

Cultural references
In August 2022, screenshots from this episode were used in social media to erroneously show that the series had predicted the 2022–2023 mpox outbreak. Instead, the screenshots from this episode showing Homer with rashes were combined with an image of Homer with a monkey from the ninth season episode "Girly Edition."
