"To Sirloin with Love" acts as the finale of "King of the Hill," but it wasn't the last episode to actually air. Four more episodes that had already been produced premiered in syndication after the fact: "The Honeymooners," "Bill Gathers Moss," "When Joseph Met Lori, and Made Out with Her in the Janitor's Closet," and "Just Another Manic Kahn-Day." These are all more ordinary episodes that don't work as well as finales as "To Sirloin with Love," but that doesn't mean they aren't still fun to watch. Hank's mother springs her announcement to remarry to a man Hank hasn't even met, Bill decides to combat his depression by getting some roommates, and Joseph's love life picks up steam.
In "Just Another Manic Kahn-Day," the actual last episode to air, the often combative relationship between Hank and his neighbor Kahn gains new dimension as the two spend some one-on-one time with each other. With Minh and Connie on a trip, Hank is tasked with checking in on his neighbor. Deciding he doesn't need his medication, Hank tells Kahn to skip it, which sends Kahn into a manic episode in which he becomes upbeat and willing to work endlessly on a shared grill project with Hank. However, Hank soon realizes he misunderstood the extent of Kahn's bipolar disorder — which is what he needs the medication for — when Kahn hits a low point and is unable to complete the project. Though Hank doesn't always behave great, he and Kahn become closer due to their newfound understanding.
