Watch it

“FlashForward” (8 p.m., ABC). This is hanging on to my must-watch list by a thread. The plot better advance tonight. The previews show a shootout and explosions, so as long as they come before the 57-minute mark . . . .

“The Office” (9 p.m., NBC). Dwight gives Jim a bizarre peace offering (um, a Trojan horse?) and Michael’s new girlfriend freaks out Pam. Because it’s almost certainly her mom.

“30 Rock” (9:30 p.m., NBC). Devin (Will Arnett) is back to torment Jack and leer over Kenneth. And a real-life porn star guests as “Porn Liz Lemon.” Yikes.

“It’s Always Sunny in Philadelphia” (10 p.m., FX). The gang protests a parking ticket they got on the night the Phillies won the World Series. I sense flashbacks of drunken hooliganism.

Record it

“Survivor” (8 p.m., CBS). There’s a huge rainstorm and Russell S. goes down with a scary injury.

“Parks and Recreation” (8:30 p.m., NBC). Leslie feels down in the dumps after a neighboring town builds a park in a day. And she’ s still staring at her pit.

“Monty Python: Almost the Truth” (9 p.m., IFC). Part 5 of the 6-part documentary focuses on the controversy over their movie “The Life of Brian.”

Skip it

“The Jeff Dunham Show” (9 p.m., Comedy Central). Ventriloquist comedy? What is this, Vaudeville? Prop comics are stupid.

“MTV’s Ultimate Parkour Challenge” (10 p.m., MTV). Sorry, but after the opening segment on the season premiere of “The Office,” I can’t take parkour at all seriously.  Take a look for yourself:
