In my humble opinion, the television year really doesn’t get under way until the season premiere of “The Simpsons” (7 p.m. Sunday, Fox). America’s favorite yellow family kicks off its 14th season with its Halloween “Treehouse of Horror XIII” trilogy.

In the first segment, a swarm of Homer clones threatens the nation’s sanity as well as its beer supply. A weak second story revolves around Lisa’s gun-control crusade. The show concludes with a witty send-up of the horror classic “The Island of Dr. Moreau.” In one scene, the evil Dr. Hibbert has turned Homer’s boss into a fur wrap. “Hey,” Bart observes, “it’s Mr. Burns, with a whole new Fox attitude!” God bless “The Simpsons.”

“King of the Hill” (7:30 p.m. Sunday, Fox) enters its seventh season with a strong episode. Hank freaks out when he catches Bobby “dirty dancing” with a classmate at a concert. Hank’s traditional values collide with those of two permissive parents (the guest voices of Debra Messing and David Herman) at the same time that Peggy tries to get her straight-arrow husband to loosen up. I am glad this smart and consistently well-written comedy has the post-“Simpsons” time slot it deserves.

Now in its fourth season, “Malcolm in the Middle” (8 p.m. Sunday, Fox) may be showing its age. Malcolm is approaching his awkward years and spends most of this first episode in an existential funk. Not even a trip to the zoo, where Lois’s old boyfriend happens to work, can cheer him up. Most of the comedy involving the four boys seems forced.

The Cartoon Network’s bizarre “Adult Swim” (10 p.m. today) animation franchise offers several reasons to stay up late on Sunday nights. Viewers who have not seen the cartoon “Aqua Teen Hunger Force” better get with the program. A deliberate spoof of animation licensing, “Force” features three hero detectives who are also fast-food products.

Turner Classic Movies unspools 24 consecutive hours of John Wayne movies, beginning 5 a.m. today with the 1932 short feature “Haunted Gold.” Fans of the Duke can enjoy his breakthrough 1939 drama “Stagecoach” (9:45 a.m.) as well as the rarely shown 1953 feature “Hondo” (7 p.m.).

The two-hour special, “TV Land Legends: The ’60 Minutes’ Interviews” (8 p.m. Sunday, TV Land) offers vintage conversations with Jackie Gleason, Jerry Seinfeld, Johnny Carson and Carol Burnett. “Legends” will return as a half-hour series at 9 p.m. every Sunday.
