Smart is apparently the new sexy. When "24" returned to the airwaves this month, Yahoo! users were searching like crazy to find info on Mary Lynn Rajskub, the actress who portrays computer geek Chloe O'Brian. And on a recent episode of "30 Rock," guest star Peter Dinklage's character noted that he dug "aggressive chicks with a nerdy vibe" after an encounter with quirky Liz Lemon. Maybe guys do make passes at girls who wear glasses. Click through this slideshow to check out some of TV's sexiest nerds.Wednesday, January, 21, 2009, 11:21 PM

"24's" Jack Bauer can't save the world alone. Fortunately, he has trusty CTU analyst Chloe O'Brian (Mary Lynn Rajskub) by his side. Although the cranky genius is stuck behind a computer most of the time, she's not your typical tech geek. No-nonsense Chloe will fight for what she believes is right, and has even proven that she knows how to wield a weapon. Now that's sexy! While a strong, intelligent woman like Ms. O'Brian might scare many men off, Chloe has had her fair share of romances. She dated Milo Pressman briefly, and revealed at the end of Season 6 that she was pregnant with her ex-husband's baby! Will motherhood soften Chloe? We sure hope not.FOX/Danny Feld - Wednesday, January, 21, 2009, 11:21 PM

Liz Lemon (Tina Fey) is rather unlucky in love, but TV viewers have fallen hard for the dorky head writer of "TGS With Tracy Jordan" and all of her quirky traits, which include being a stress eater, being allergic to "anything warm and adorable," and having dressed up as Princess Leia four Halloweens in a row. Although she's obviously a smart and clever writer, Liz has a penchant for sticking her foot in her mouth. Her boss, Jack Donaghy, has even described Liz as being "socially retarded." Although Donaghy encourages her to wear more feminine attire, we love Liz just the way she is. The fact that the "30 Rock" character is based on Fey's real-life experience as the former head writer of "SNL" makes both Liz and Tina all the more endearing.NBC/Nicole Rivelli - Wednesday, January, 21, 2009, 11:21 PM

Dr. Temperance Brennan (Emily Deschanel) is a brilliant forensic anthropologist who is called in to help when CSI gives up on identifying a badly decomposed body. In addition to reading bones, Brennan is a best-selling novelist who speaks at least six languages, is a licensed hunter, and is trained in three types of martial arts! In spite of all her incredible talents, she lacks social skills, is completely unaware of pop culture, and often has trouble understanding jokes and sarcasm. Still, handsome FBI Special Agent Seeley Booth can't help but be attracted to his odd partner, whom he affectionately calls "Bones."FOX/Carin Baer - Wednesday, January, 21, 2009, 11:21 PM

Pam Beesly (Jenna Fischer) isn't your stereotypical "Office" geek, but we think it's safe to say that the frustrated receptionist of Dunder Mifflin's Scranton branch is a nerd at heart. In addition to playing solitaire on her work computer, Pam gets a big kick out of playing office pranks. One area where she lacks a sense of humor is when it comes to kitchen cleanliness. This season she felt the need to leave an anonymous note reprimanding the employee who made a mess in the office microwave. Only a dork would do that! Regardless, Pam's girl-next-door vibe has resulted in several of her co-workers crushing on her, from current fiancé Jim Halpern to HR rep Toby Flenderson.NBC/Chris Haston - Wednesday, January, 21, 2009, 11:21 PM

CNN anchor Campbell Brown is far more than a pretty talking head who reads the news off a teleprompter. This beauty won an Emmy for her on-the-scene coverage of Hurricane Katrina and she's a virtual encyclopedia of current events knowledge -- able to talk U.S. politics, world affairs, and controversy with the best of 'em -- who gives both sides of the aisle a run for their money. And she's not alone. Plenty of sexy women -- from Paula Zahn to Ashleigh Banfield to Julie Chen to Rachel Maddow -- are news nerds at heart. E.M.

Dr. Elliot Reid of "Scrubs" is a successful doctor at Sacred Heart Hospital who also happens to be incredibly gorgeous… and neurotic. The self-proclaimed WASP has a habit of telling long, pointless stories and isn't known for having the best bedside manner. Although "Dr. Barbie" tries to inspire both the hospital staff and her patients with uplifting tales, they often result in someone killing themselves. Thanks to an alcoholic mother, who often pressures Elliot about her looks and love life, Dr. Reid also has serious insecurities when it comes to s-e-x, referring to private parts with such silly names as bajingos and caboodle. Regardless, the men of Sacred Heart love her… especially fellow geek Dr. John Dorian (J.D.).ABC/Scott Garfield - Wednesday, January, 21, 2009, 11:21 PM

When you're a forensic scientist who dresses with a gothic sense of style, you pretty much have no choice but to be a nerd, and that's definitely the case for Abby Sciuto (Pauley Perrette) of "NCIS" who admits to having had THREE majors in college -- sociology, criminology and psychology in addition to a Master's Degree in criminology. Holy text books! But with her pig tails, school-girlesque outfits, and hints at tattoos in hidden places, she's one scientist the fellows in this male-dominated field definitely don't mind working alongside.CBS/Monty Brinton - Wednesday, January, 21, 2009, 11:21 PM

Despite her gawdy red-framed glasses, mouth full of metal, unruly hair, and Guadalajara poncho, Betty Suarez (America Ferrera) managed to turn MODE magazine upside down and right side up with her 'can do' attitude, heart of gold, and girl-next-door charm. And more than just the fashion world has taken notice of "Ugly Betty." She's had at least three suitors – Walter, Henry, and Gio – vying for her love, proving that smart, good-natured girls are attractive (and can get marriage proposals!) even without Prada.NABC/Patrick Harbron - Wednesday, January, 21, 2009, 11:21 PM

There's no doubt that one of the smartest citizens in Springfield is Lisa Simpson. She's a stellar student, has a strong passion for social justice, and is probably the only self-aware member of the "Simpson" brood. On the surface Lisa may seem like a typical nerd, but this red dress-wearing gal is an artsy musician who can be seen rocking out to "Welcome to the Jungle,” playing soulful blues on her saxophone and even participating in sports like hockey. That's probably why the boys are secretly ga-ga for her and the girls are just jealous of her – hence the reason Lisa has no friends…FOX - Wednesday, January, 21, 2009, 11:21 PM

When Neela Rasgotra arrived at "ER's" County General as a medical student from London during the series' tenth season, it was clear she was a book smart doctor-in-training who struggled socially. But, oh, how times have changed. Neela (played by Parminder Nagra of "Bend it Like Beckham" fame) has gone on to hook up with many of the hospital's hottest doctors, some of whom have fallen head over heels for the brainy babe. She married soldier Michael Gallant (Sharif Atkins) and didn't let a little thing like becoming a widow slow her down when she later took up with hotties Dr. Ray Barnett (Shane West), Dr. Tony Gates (John Stamos) and the show's new Aussie hunk Dr. Simon Brenner. Guess Neela's got more than just healing powers...NBC/Justin Lubin - Wednesday, January, 21, 2009, 11:21 PM
