Watch it

“How I Met Your Mother” (8 p.m., CBS). Marshall becomes a rabid environmentalist, Ted has an encounter with the jilted Captain, and Barney actually has a crush on that girl he met last week.

“The Chicago Code” (9 p.m., Fox). This is a good show, but I’m still not completely sold yet. I’m waiting for it to find its feet and really get the story going. And one thing that bugs me: All the Irish mob guys have long, greasy hair. Come on, if you know anything about Irish goons (or ever watched “Brotherhood”), you know they should all have little more than stubble on their heads. Tonight, Jarek and Luke Cafferty chase a bank robber, and Chief Teresa is forced to work with Gibbons.

Record it

“World’s Deadliest Towns” (5, 6 and 7 p.m., repeated from 8-11 p.m., Animal Planet). Series premiere. Back to back to back episodes — call it a one-night miniseries — about, yes, the towns where you’re most likely to be killed by wild animals. First, it’s stampeding elephants in India, then killer hippos in Zambia, followed by man-eating tigers in India. And yes, hippos are the most dangerous animal in Africa.

“Chuck” (8 p.m., NBC). Valentines’ Day comes a week late. Way to go, NBC scheduling department. Anyway, Chuck’s romantic plans with Sarah are disrupted when he has to protect an heiress.

“Mad Love” (8:30 p.m., CBS). The premiere fell flat, despite the super likable cast. I’ll give it a little time and hope it can develop into something good, but the track record of multiple-couple romantic comedies this season hasn’t been good. (See: “Perfect Couples” and “Traffic Light.”)

“Top Gear” (8:40 p.m., BBC America). The guys go to Albania to test super-luxury cars. Because when you think of super luxury, you naturally think of Albania.

“Gossip Girl” (9 p.m., The CW). Eric celebrates his 18th birthday while being incomprehensibly blackmailed by Damien, Serena is torn as usual between her family and her wanna-be boyfriend (this time it’s Ben, the guy who was framed and locked up for years and now harbors no resentment, even though he has to register as a sex offender for the rest of his life) and Blair pursues her lofty ambitions at W magazine. Sometimes, this show makes me want to bang my head against a wall.

Skip it

“The Bachelor” (8 p.m., ABC). With crazy Michelle gone, it’s down to the (mostly) sane final four. Tonight Brad visits their families, where he meets a wary dad and a skittish daughter.

“The Unpoppables” (8 and 8:30 p.m., TLC). This reality show about people who make balloon sculptures debuted last week. I missed it, but I wouldn’t say I missed it, you know?

“Amanda Knox: Murder on Trial in Italy” (9 p.m., Lifetime). It’s got a clunky title and Hayden Panetierre starring — those aren’t good starting points. In case you missed the news, it’s the ripped-from-the-headlines “true” story about a Seattle exchange student who gets accused of a grisly murder in Italy, so count on it being plenty trashy and exploitative.
