Dr. Temperance "Bones" Brennan and Special Agent Seeley Booth (Emily Deschanel and David Boreanaz), Bones
Forget the coma sex. These two have a professional rapport of equal parts mutual respect and flirtation. Producers say the pair have a rocky season ahead, as they sort out their complicated feelings. In the meantime, watch and enjoy as the dream of a Bones-Booth hookup remains alive.

Sylar (Zachary Quinto), Heroes
This skull-splitting hottie has made evil incarnate sexy with a simple furrow of his substantial brow. Though the show has attempted to show the vulnerable, tortured sides of the erstwhile Gabriel Gray, but what fun is that? Watching Quinto bring an unrepentant murderer to life is what earned him a spot on this list.

Sam and Dean Winchester (Jared Padalecki and Jensen Ackles), Supernatural
Sure, they aren't exactly cops, and the crimes they solve aren't the most realistic on TV, but whenever the hunky brothers are called to fight supernatural evil, we can't stop watching.

Damon Salvatore (Ian Somerhalder), The Vampire Diaries
With a sharp wit and piercing eyes, Damon Salvatore's blood-sucking ways are turning Mystic Falls into a graveyard one sexy bite at a time. "That's for me to know and for you to dot-dot-dot," he says with a smirk of his modus operandi.

Sarah Walker (Yvonne Strahovski), Chuck
Sarah can look hot in barely-there lingerie, lederhosen, a Princess Leia get-up and braces — and kick ass doing it. The blonde-haired, blue-eyed Sarah is easy on the eyes as is, but when she starts busting out her lethal martial arts moves, she earns the nickname "Stra-hot-ski."

James "Sawyer" Ford (Josh Holloway), Lost
James' shifting identity — he's a con man known as Tom Sawyer; no, he's a Dharma Initiative bossman known as Jim LaFleur — has only increased his allure. While his criminal past could be behind him, a rumored alternate timeline could mean we haven't seen the last of his scheming

Det. Olivia Benson (Mariska Hargitay) and Det.Elliott Stabler (Christopher Meloni), Law & Order: Special Victims Unit
They've got each others' backs as partners on the SVU, but it's hard to miss the sexual tension they share. Will they ever seal the deal? Producers always answer with a solid maybe, giving fans hope of a different kind of partnership.

Kate Austen (Evangeline Lilly), Lost
How bad is Kate really? Sure, she burned her mom's house down, murdering her abusive stepfather, and conned countless others in her global quest for inner peace, but those handcuffs must really chafe her slender wrists. Give our girl a break! Since the crash of Oceanic 815, Kate has showed remorse for her actions. Plus: She's a mother, people! (Oh, wait... that was a lie. Details!)

Richard Castle and Det. Kate Beckett (Nathan Fillion and Stana Katic), Castle
Beckett does things by the book; Castle just writes about them. Even though he's the brains behind a successful mystery novel series, she's the one who usually pieces together the real-life murders. But they both look awesome doing it.

Derek Morgan (Shemar Moore), Criminal Minds
First off, we'd like to thank the Criminal Minds wardrobe department for always putting the ultra-dishy Shemar Moore in too-tight T-shirts that perfectly accentuate his guns. Secondly, we'd like to thank the writers for putting those guns to use by having Morgan tackle practically every unsub on the show. Is it too much to ask for more shirtless-ness?
11 of 14 CBS
Tony DiNozzo (Michael Weatherly), NCIS
What's sexier than a sense of humor? DiNozzo may be super-dedicated to stopping domestic and international crime, but at least he doesn't take himself to seriously doing it. The fact that he looks good while cracking wise doesn't hurt.
12 of 14 Glenn Watson/USA Network
Fiona Glenanne (Gabrielle Anwar), Burn Notice
Fiona is one vixen who knows how to use her sex appeal -- and firearms, explosives and her lock-picking skills. A former IRA operative, her freelance work has afforded her much more excitement, in the sultry climes of Miami.
13 of 14 Colleen Hayes/Warner Bros./CBS
Patrick Jane (Simon Baker), The Mentalist
Yes, Patrick Jane's one perceptive cookie, but his biggest crime-solving weapons are his killer (no pun intended) smile and luscious sun-kissed locks. How can you not get distracted by that during interrogation?

Catherine Willows (Marg Helgenberger), CSI: Crime Scene Investigation
She got her start as an exotic dancer — how could she not be on this list!? And now this formidable woman heads up Las Vegas' CSI night shift. She shared a close friendship with the inscrutable Gil Grissom (William Petersen), her former boss, before he left the office, but can someone please get this lady a love interest?
