* Chuck (8 pm/ET NBC)
Chuck takes a walk on the mild side, leaving the hustle and bustle of the big city for the quietude of sunny suburbia. Chuck and Sarah go undercover as a happily married couple (a dream come true for Chuck?) in an outlying residential community. But do dark forces lurk under the green-grass splendor? On the surface, at least, there's a merry neighbor (Andy Richter) and a seductive siren named Sylvia (Jenny McCarthy), a cougar-in-training who sets out to win Chuck's affections. Meanwhile, Valentine's Day was just honored, but there's no love in the air here: Big Mike's wife files for divorce, driving the Buy More bigwig into an overly foul funk.
* House (8 pm/ET Fox)
Foreman hasn't been thinking very clearly lately. Falling for a woman - a colleague, no less - who's suffering from the very disease you're studying could do that to you. House had to save Foreman from throwing away his career in the last episode, and he'll wade deeper into the Foreman-Thirteen swamp tonight. In his day job, meanwhile, House must diagnose a dying priest who says he saw a bleeding Jesus. It seems that the padre has lost faith, and that's got to interest House.
Bells will soon ring for a belle. Sassy Southerner Brenda Leigh Johnson preps for her upcoming wedding with help from her visiting parents (Frances Sternhagen and Barry Corbin, in their recurring roles). Also materializing is Fritz's sister, Claire (Amy Sedaris), a vegan who claims to be a psychic, or in her words - an "intuitionist." Clairvoyant Claire taps into her presumed gift, helping a scrambling Brenda prevent a murder from occurring. And though Claire's paranormal power is questioned, she is able to read Brenda like a book. - Dean Maurer
* Right America: Feeling Wronged - Some Voices from the Campaign Trail (8 pm/ET HBO)
Today may be Presidents' Day, but the folks that Alexandra Pelosi (The Trials of Ted Haggard) speaks to in her latest documentary probably won't have it circled on their calendars. Filmed in the run-up to the 2008 election, Pelosi goes to McCain-Palin rallies, NASCAR parking lots and all over Red America, where she listens to conservatives fret about the direction of the country and declare, often in no uncertain terms, their opposition to Barack Obama's candidacy.
* Spectacular! (8 pm/ET Nickelodeon)
The world of rock bands clashes with the world of show choirs in this upbeat teen musical. The pairing starts when a wannabe rocker named Nikko (Nolan Gerard Funk) gets kicked out of his band. Sunny show-choir leader Courtney (Tammin Sursok) sees this as the perfect opportunity to get Nikko to join her group, which goes by the name of Spectacular! Nikko reluctantly agrees in order to make some cash, but soon his loyalty is put to the test when his two very different worlds collide.
