The Big Bang Theory (CBS, 8 p.m.) -Leonard's dreams come true when he and Penny go on their first date.

Gossip Girl (The CW, 8 p.m.) - When Dan starts talking to a new girl, Blair calls out the bitch squad.

Terminator: The Sarah Connor Chronicles (Fox, 8 p.m.) - Cromatie kidnaps Penny from Lost as bait to attract the Connors.

How I Met Your Mother (8:30 p.m.) - Nothing brings us more pleasure than Barney squirming with feelings for Robin.

Heroes (NBC, 9 p.m.) - Can the show jump back from last season's sophomore slump? We sure hope so. By the way, although NBC has been touting tonight's season premiere as a three-hour event, the first hour at 8 p.m. is basically a clip show hosted by the cast.

One Tree Hill (The CW, 9 p.m.) - Haley looks into Dan's disappearance. She is going to be pissed when she finds Carrie.

Worst Week (CBS, 9:30 p.m.) - Sam doesn't have the best luck. Too bad he still has to tell his girlfriend's parents, who don't like him very much, that they're engaged and expecting a baby.

90210 (The CW, 8 p.m.) - Ty and Annie grow closer. Will they do it? Nah, it's not the Spring Dance yet.

Privileged (The CW, 9 p.m.) - Megan flirts with the girls' new headmaster (former Real World-er and Grey's Anatomy's gay solider David Giuntoli).

Fringe (Fox, 9 p.m.) - Things would just be too easy if there was a guy who could predict Pattern-related catastrophes before they happen, so we're guessing the guy who can do just that in tonight's episode is not all that or is going to meet a bad end.

The Mentalist (CBS, 9 p.m.) - Simon Baker is a former fake psychic who uses his keen observation skills to help solve crimes. Yes, it's Psych, but serious.

Law & Order: SVU (NBC, 10 p.m.) - Luke Perry guest stars as a man who may be abusing his foster child. Kelly, is this a guy you want in your son's life?
