“The Challenge: Rivals” (9 p.m., MTV): I’m not entirely proud of this, but I have not missed an episode this summer. I watch for Kenny Santucci, who should be cast in a (non-dancing) remake of “Saturday Night Fever,” and CT — who erotically enslaves every woman by just standing there.
“Friday Night Lights” (9 p.m., TNT): The movie, set in 1988, with Billy Bob Thornton and Tim McGraw.
“Confessions: Animal Hoarding” (9 p.m., Animal Planet): Updates from fan favorites — including the guy with more than 100 chickens!
