Watch it

“How I Met Your Mother” (8 p.m., CBS). Ooooh, a special musical episode that features Barney dancing around singing about his love of suits. It’s a 100th episode spectacular, with guests Tim Gunn, Rachel Bilson and Stacy Keibler. Sounds oddly fun, count me in.

“Fringe” (9 p.m., Fox). On a special night. Tonight, a teenage girl mysteriously gets a brainful of classified military information. Hmmm, sounds like the setup to “Chuck.”

“No Reservations” (10 p.m., Travel Channel). Season premiere. Tony’s in Panama as the sixth season kicks off. Bet you a dollar we’ll see some fried plantains.

“The Daily Show” (11 p.m., Comedy Central). The guest is Bush administration torture-memo author John Yoo of UC Berkeley. Hmmm, this could get interesting.

Record it

“Chuck” (8 p.m., NBC). Chuck has to protect a visiting dictator (the ever suave Armand Assante) from assassination. Meanwhile, Captain Awesome is loving knowing Chuck’s secret a bit too much.

“Diners, Drive-Ins and Dives” (10 p.m., Food Network). For months I’ve been watching and waiting for Q, a fave restaurant in my SF neighborhood, to be featured (they filmed there last summer). Tonight’s show features an SF eatery with tasty roasted pork. Hmmm, this could be it . . . .

“Men of a Certain Age” (10 p.m., TNT). Joe goes on a disastrous date. Hilarity (followed by a moment of poignancy) ensues.

Watch the last five minutes

“Tonight Show with Conan O’Brien” (11:35 p.m., NBC). Vampire Weekend perform. Hipsters everywhere rejoice.

Skip it

“The Bachelor” (8 p.m., ABC). The episode where we find out one chick is getting kicked off for hooking up with someone on the production team. Sordid, sure, but it’s been turned into a publicity bonanza. Don’t get sucked in.

“The Jay Leno Show” (10 p.m., NBC). With guest Bill Cosby.  Be careful if you watch in HD, Cosby’s sweater could make your TV explode.
