The new comedy “The Loop” (8:30 p.m., Fox) simply oozes with contempt for its young characters and its target audience. Sam (Bret Harrison) is the first of his clique to find a good job. It’s not merely a job. Apparently, his college thesis was so impressive that he’s now on the board of directors of a major airline. If you believe that, you’ll have no problem accepting the fact that his administrative assistant, Darcy (Joy Osmanski), is a brilliant, underutilized MIT graduate. We’re supposed to laugh at her suffering.

When Sam isn’t at work, he’s with his pals, who seem to live a “Groundhog Day” existence in which every night is a bachelor party, an endless round of binge drinking and carousing. Sam’s older brother, Sully, is a one-note “whoa, dude” party-animal stereotype. Bartender Lizzy (Sarah Mason) also lives with them. She’s gorgeous and blonde and as dumb as a brick. Piper (Amanda Loncar) is supposed to be a medical student, but she’s never seen with a book. She’s carrying on a long-distance relationship with another guy. She doesn’t seem to notice that Sam has been in love with her since college.

If tonight’s pilot, about a surprise party for Piper, is merely mediocre, a second episode, about Sam’s unhinged dalliance with a liquor promoter, is completely unwatchable.

Twenty-somethings are a hard audience to reach. Not yet settled down, they’re often juggling many activities. You’ll notice that none of the characters on “The Loop” ever sits still long enough to watch television. And I’m sure none of them would be caught dead watching something as lame as “The Loop.”

¢ Fox’s drama “Prison Break” returns to the schedule Monday. Those of you who need a refresher course or did not have time to keep up with the show’s first 13 hours can catch up with “Prison Break: Unlocked” (9 p.m., TV Guide Channel).

¢ The parents of those McCaughey septuplets are slackers compared with Michelle and Jim Bob Duggar of Fayetteville, Ark., the subject of the documentary “Raising 16 Children” (7 p.m., Discovery Health). If they look familiar, you must have seen their earlier film, “14 Children and Pregnant Again!”
