1) “It’s Always Sunny in Philadelphia,” 9 p.m., FX and FXX. The gang is sort of in its natural habitat here — a Renaissance fair (shown here), where weirdness is normal. Naturally, they take it too far, in an episode that’s erratic, but quite funny. That’s followed by a good “Adults” rerun, with Anton finding that people do, unfortunately, sometimes listen to him.
2) “Jeopardy Masters,” 8-11 p.m., ABC. On Tuesday, the show will find its $500,000 winner. First, here are reruns of the games that set it up — the last quarter-final onees from 8-9 p.m., then the semi-finals from 9-11.
3) “Schitt’s Creek” (Pop) and “Yellowstone” (Paramount Network), 11 a.m. Both series — triumphs of comedy and drama — wrap up reruns of all their episodes. “Creek” has its fifth season, then its sixth and final one — the one that swept the Emmys — from 6 p.m. to 1 a.m. “Yellowstone” continues its Costner episodes until 6 p.m. then its post-Costner ones to 12:15 a.m.
4) “All American,” 8 p.m., CW. Three weeks from the series finale, the Baker family crisis builds. Cassius must choose between Bakers and his own family; Layla’s attempt to keep Jordan calm backfires. Also, Coop scrambles to find Spender.
5) More: The Disney Channel reruns two recent musicals back-to-back — “Descendants: Wicked Wonderland” at 7 p.m. and “Camp Rock 3” at 8:45. And at 10, PBS’ “POV” has the acclaimed “Remake.” Ross McElwee’s documentaries often included his son Adrian. After Adrian’s death (at 27, of a fentanyl overdose), Ross re-examines his son’s life on film.
