It’s President’s Day! Name the worst TV president ever—as in, a president of the United States character, not some clown who ran a perfectly good TV network into the ground (cough, NBC!, cough). And … go. ---

What’s new tonight:
Chuck (NBC) Last week, Chuck got sexy with a team of leather-clad female agents (including Sarah); this week, Chuck and Sarah go even sexier, undercover at an Eyes Wide Shut party on … Valentine’s Day? Can’t NBC get anything right? Christ …

House (Fox) Who knows why, but Dr. House is going to a local school’s Career Day. Hey, if it involves Hugh Laurie yelling at fifth-graders for an hour, I’m there.

Hawaii Five-0 (CBS) Danno’s (Scott Caan) younger brother, who also happens to be the subject of an FBI investigation, drops by. Baby bro is played by, would you believe … Dane Cook? That’s right—the comedian you loved in college is “acting” again. After several months of just fast-forwarding to the parts with Grace Park in a bikini, I just might have to watch a full Hawaii Five-0 for this.

Also new tonight:
The Bachelor, Castle (ABC); How I Met Your Mother, Mad Love, Two & a Half Men, Mike & Molly (CBS); The Cape, Harry’s Law (NBC); The Chicago Code (Fox); 90210, Gossip Girl (The CW); Greek, Pretty Little Liars (ABC Family); Intervention, Heavy (A&E); Cake Boss (TLC); Skins (MTV)

Preview: Dane Cook drops in on Hawaii Five-0. Next week: Zach Galifianakis as an evil manatee!
