Psycho Wedding Crasher. Could my search for the ultimate Lifetime movie be over? 27 Dresses meets Misery as Heather Morris (Glee, Dancing with the Stars) and Joan Van Ark star in the story of a bridal dress seamstress (Morris) who dreams of a groom of her own — and who'll stop at nothing to get him. 8 p.m. Sunday, Lifetime.

Broad City Marathon. Wayne's Abbi Jacobson and her partner-in-comedy Ilana Glazer will be back for a fourth season on Sept. 13. Until then, there's this Labor Day marathon of Seasons 1-3. 9 a.m. Monday, Comedy Central. 

TCM Remembers Jerry Lewis. For decades Labor Day weekend belonged to Jerry Lewis' annual telethon to raise money to fight muscular dystrophy. The classic-movie channel honors the actor and comedian, who died Aug. 20, with an evening that kicks off with The Nutty Professor (1963), followed by The King of Comedy (1983), The Stooge (1952), The Bellboy (1960),  and The Disorderly Orderly (1964). 8 p.m. Monday, TCM.

American Horror Story: Cult.  The premiere's set on Election Night 2016 and Sarah Paulson, Alison Pill, and Billie Lourd all play cartoonishly liberal characters horrified by the results. (Not everyone is.) Trigger warning: There will be killer clowns. AHS, now on its seventh edition, still isn't my thing, but the sets, which I visited with other reporters this summer, are wonderful — keep your eyes peeled this season for the thematically perfect bookcase in the main characters' living room. 10 p.m. Tuesday, FX.

You're the Worst. The anti-romantic romantic comedy is back for a fourth hilariously heart-rending season. The hourlong premiere picks up some time after Jimmy (Chris Geere) abandoned Gretchen (Aya Cash) on the hillside where he'd just proposed. 10 p.m. Wednesday, FXX.

One Mississippi. Comedian Tig Notaro returns for another season of fish-out-of-water comedy as her semi-autobiographical character's radio show pushes boundaries in Biloxi, Miss. Friday, Amazon.
