ONE HUNDRED YEARS ago this weekend, the trenches fell silent. The war to end all wars was over. In addition to marking the end of a conflict that killed tens of millions, the armistice of Nov. 11, 1918, began a peace process that reshaped the world in ways still being felt. Wars rage in the Middle East within and between countries whose borders were hastily drawn up during the negotiation of the Treaty of Versailles.

To commemorate this world-shaping event, the History Channel partners with Ford to devote its entire Saturday and Sunday prime-time schedule to “Truck Weekend in America.” Truck enthusiasts put their vehicles to the test in different off-road challenges on two helpings of “Truck Night in America” (8 p.m. Saturday and Sunday, History). Saturday night culminates in an hourlong commercial, “Born Tough: Inside the Ford Factory” (10 p.m.).

I’m not sure “The Simpsons” could concoct a crueler parody of what the History Channel has become. It’s time for History to rename itself, since it’s already “rebranded” itself. Calling it History amounts to consumer fraud.

• The Smithsonian Channel manages to honor veterans and still celebrate restored vehicles with “Gun Trucks of Vietnam” (9 p.m. Sunday). This hourlong documentary profiles the unheralded crews of truck convoys who found that their vehicles were ill-suited and under-armored for ferrying men and equipment into jungle terrain. They scavenged parts and weapons to turn their trucks into 5-ton fighting machines, which saw a great deal of action.

Next weekend, Smithsonian will return to Vietnam with another installment of “The Lost Tapes,” covering the Tet Offensive of 1968.

• Fans of unceasing embarrassment, prolonged social discomfort and exquisite torture should not miss “Sally4Ever” (10:30 p.m. Sunday, HBO, TV-MA).

We know we’re in for a world of pain when “Sally” begins with an extended performance by a male a cappella group, singing George Michael’s “Faith” with all of the erotic verve of a barbershop quartet.

The lack of passion — titillating and otherwise — pretty much defines David (Alex Macqueen), Sally’s (Catherine Shepherd) spineless boyfriend. Together for a decade, their moments of shared intimacy consist of David shaving his calloused feet in her presence and making any number of off-putting grunts and other bodily noises.

Just as David gathers enough gumption to propose, Sally, a put-upon marketing assistant for a spectacularly unglamorous advertising firm, embarks on a sexy adventure with bar band singer Emma (series creator Julia Davis).

Their unbridled romp is depicted as ridiculously as possible, unfolding as savage parodies of cinematic sex scenes and perhaps send-ups of the awkwardness of sex itself.

Fully awakened as a woman, Sally manages to tell David that she hasn’t found him attractive, “for maybe the past seven years.” But having left the frying pan of dull domesticity, she jumps into the fire of cohabitation (in David’s house!) with a full-fledged sociopath. The scene where Sally introduces Emma to her starchy parents is almost unendurable.

Made for Sky TV in the United Kingdom, “Sally” offers a weird combination of British understatement with broad physical comedy and brazen scatological humor. To American viewers, it may seem both overly subtle and utterly obvious at the same time. Clever and crude, it’s also far crueler than most U.S. fare.

• National Geographic invites viewers to spend two Sunday nights in the hermit kingdom, airing four hours of “Inside North Korea’s Dynasty” (9 p.m. and 10 p.m. Sunday, concludes Nov. 18).
