Goodbye, Hank Hill, we’re gonna miss you. Sunday night, after 13 terrific seasons and more than 250 episodes, Fox’s animated series “King of the Hill” (second-longest running cartoon behind “The Simpsons”) closes the page on middle-American life in the small town of Arlen, Texas. Hank will join his buddies Dale, Bill and the dialogue-challenged Boomhauer by the fence, drinking Alamo beer for the last time as the Refreshments theme music “Yahoos and Triangles” plays in the familiar title sequence. Hank, the pot-bellied propane salesman in the omnipresent white t-shirt, wife Betty and 13-year-old son Bobby will amble through two final satisfying episodes. “King of the Hill,” unlike a lot of current animated series, moved at its own pace and was never mean-spirited. The show was created by Mike Judge (who was coming off “Beavis and Butthead”) and Greg Daniels (Conan O’Brien’s roommate at Harvard). When the show debuted in 1997, Daniels summed it up nicely: “He’s [Hill] upset about how America is changing, and he doesn’t know what to do about it. The theme of the show is populism and common-sense Americans versus the silly elite.” Hank’s common sense usually won.
