“Saturday Night Live in the 2000s: Time and Again” (KOB-4 8 p.m.) Sure, generally speaking, it’s been a disappointing decade. ... But you get to see “Dick in a Box” again!
“Supernatural” (KWBQ-19 8 p.m.) Ghost- (and other stuff-)busting bros Dean and Sam enter their 100th episode stuck between a rock and a hard place (or Satan and the Archangel Michael, as the case may be).
“Green Day Rocks Broadway” (MTV 8 p.m.) Nothing cements your punk rock cred like a show on Broadway.
“The What Not to Wear Awards” (TLC 7 p.m.) Sounds better than “Another What Not to Wear Clip Show.”
Secrets of the Mountain (KOB-4 7 p.m.) Barry Bostwick, Paige Turco and three kids go all Indiana Jones and Family in this made-for-TV adventure pic about a search for ancient treasure.
“The Whale That Exploded” (National Geographic 7 p.m.) Worst fairy tale ever.
“Doctor Who” (BBC America 7 p.m.) David Tennant steps out of The Doctor’s shoes, and this new kid Matt Smith takes over. So far, all signs point to “good.” But we’ll know more about his big-chinned newbie after tonight’s long-awaited season premiere.
Riverworld (SyFy 7 p.m.) SyFy adapts Philip José Farmer’s much-beloved fantasy novel franchise into a two-part mini-series starring some the requisite random sci-fi actors (Tahmoh Penikett from “Battlestar Galactica,” Laura Vandervoort from “V”). Hope it’s better than the 2003 attempt.
Beauty & The Briefcase (ABC Family 6 p.m.) Hilary Duff stars in this cheesemont made-for-TV movie about a fashion journalist who lands a corporate job for an undercover article about dating co-workers. Gee, I wonder if she actually falls in love with one of her co-workers, then gets exposed as a fraud, then hooks up again with him in the last five minutes?
“Donald J. Trump’s Fabulous World of Golf” (Golf Channel 7 p.m.) Tonight, George Lopez plays a round with Oscar De La Hoya. And why aren’t we watching “Emeril Lagasse’s Fabulous World of Celebrities Eating” as well? Or “José Eber’s Fabulous World of Famous Haircuts”? ... Honestly, TV, I can spit out this stuff all day.
“Top Gear” (BBC America 6 p.m.) In this special, 100-minute ep, the boys brave drug lords, flash floods and perilous heights to race through the Bolivian rainforest.
“Glee” (KASA-2 8 p.m.) “Glee” finally returns for another season with an all-Madonna episode.
“American Idol: Idol Gives Back” (KASA-2 7 p.m.) Sounds better than “American Idol: Producers Stretch Another Episode out of the Series.”
Food, Inc. (KNME-5 8 p.m.) Authors Eric Schlosser and Michael Pollan offer their insight into today’s world of corporate farming in this entertaining, attention-grabbing 2009 documentary about American eating.
