“Wipeout” (8 p.m., ABC). Think of it as a brain sorbet, to cleanse the palate.
“The Office” (9 p.m., NBC). Andy starts a small-business seminar, and desperately seeks guest speakers. What he ends up with instead is Michael and Holly doing improv, along with . . . . wait, what’s this? The original boss/entertainer, David Brent! Yep, Ricky Gervais reprises his role from the original “Office.” Awesome.
“Parks & Recreation” (9:30 p.m., NBC). Pawnee is struck by a flu epidemic, which knocks Leslie down but not out. And Ron and Andy somehow bond.
“30 Rock” (10 p.m., NBC). Tracy gets followed for a reality show, and Jack tries to make a quick buck off a disaster-relief telethon.
“Community” (8 p.m., NBC). The gang help Annie stage an anti-drug play at a local middle school, and things go, predictably, awry. And who comes in to save the day? Senor Chang.
“Archer” (10 p.m., FX). Season premiere. This would be a “Watch it” if not for “30 Rock.” I loved this show last year, it’s an incredibly funny animated workplace comedy involving inept spies. It’s sick, it’s raunchy and it’s brilliantly written. As much as I like the NBC comedy block, this might be the funniest series currently on TV.
“Jersey Shore” (10 p.m., MTV). Ronnie and J-Woww make up, which sends Sammi into a meltdown. And Pauly D unveils the “grenade whistle.” Which is more like a horn, followed by him shouting “Grenade whistle!” Heh.
“Brad Meltzer’s Decoded” (10 p.m., History). Examining the secret Bohemian Grove gathering near Guerneville, where the rich and powerful sacrifice babies, worship the devil and plot world domination. Um, or else they just lounge around in the redwoods and get drunk.
“Real Houewives of Beverly Hills” (9 p.m., Bravo). Part 1 of the gripping two-part reunion show. Ugh.
