Nobody holds a grudge like a country singer. That’s the gist of “CMT Most Shocking: Feuds” (7 p.m., CMT). After a nod to the legendary tiff between the Hatfields and the McCoys, “Feuds” gets right down to dishing the dirt on the love-triangle tussle between Mac Davis and Glen Campbell; bad feelings between singer Brad Paisley and songwriter Richard Marx; the melee between the mullet-maned stars Travis Tritt and Billy Ray Cyrus; and even the pitched battle for custody of a frozen pet that roiled the waters at the Jim Reeves Museum.

Much is made of the very expensive estate battle between Hank Williams Jr. and Jett Williams. Jett hopes someday for a reconciliation and sees a day when “we’ll be able to put everything behind us and maybe go fishing.” The press material for “Feuds” makes no mention of the recent red, white and blue brawl between Toby Keith and Natalie Maines of the Dixie Chicks.

• Turner Classic Movies holds a mini-marathon of Abbott and Costello movies, beginning with the 1941 comedy “Buck Privates” (7 p.m.). This Army comedy also features Three Stooges player Shemp Howard, as well as the Andrews Sisters.

The shenanigans continue with two horror spoofs, “Abbott And Costello Meet the Invisible Man” (8:30 p.m.) and “Abbott And Costello Meet the Mummy” (10 p.m.), followed by “Abbott And Costello In the Foreign Legion” (11:30 p.m.).
