1 of 18 Adam Taylor/Fox
Thirteen (Olivia Wilde) from House
Yeah, she's hot, but Thirteen has overcome some seriously crazy storylines this season (Huntington's disease, temporary lesbianism) and came through it all OK.
2 of 18 The CW
Lucas and Nathan Scott (Chad Michael Murray and James Lafferty) from One Tree Hill
Between Lucas' brooding charm and intelligence and Nathan's loving and fatherly demeanor, who wouldn’t want the sexy Scott brothers in their home every Monday night?
3 of 18 Michael Courtney/The CW
Chloe (Allison Mack) from Smallville
She was Smallville's girl next door, but once she got some powers she took on a whole new sexy edge. Either way, she's super!
4 of 18 Carin Baer/AMC
Don Draper (Jon Hamm) from Mad Men
He smokes, drinks, gets any woman he wants, takes three-martini lunches and is unquestionably the best in his line of work. Jealous yet? Let's see you take three weeks off work without explanation and not get punished.
5 of 18 Justin Stephens/Sci Fi
Six (Tricia Helfer) from Battlestar Galactica
Sexy Cylon Six really needs no introduction. She's platinum blonde, gorgeous, as tall as the day is long, and wickedly appealing in her red cylon dresses. We just wonder what she sees in Baltar?
6 of 18 Randy Holmes/ABC
Dr. Derek Shepherd (Patrick Dempsey) on Grey's Anatomy
The man McDreams are made of. He's brainy (by nature and by profession), his hair is always perfectly coiffed and you know he's patient after putting up with Meredith this long.
7 of 18 Joel David Warren/Warner Bros.
Mick St. John (Alex O'Loughlin) from Moonlight
Let's see. He's gorgeous, protects the ones he loves and just so happens to be a vampire, one of the most culturally relevant creatures on the planet right now. He's undead sexy!
8 of 18 Art Streiber/ABC
Kate (Evangeline Lilly) from Lost
Even though she looks like she could benchpress 220, we still adore this freckle-nosed, pint-sized cutie. Who wouldn't want to be stranded on an island with her?
9 of 18 Randy Tepper/Showtime
Hank Moody (David Duchovny) from Californication There's bad boys, and then there's Hank Moody. Despite his sexual escapades, he does have the best intentions regarding his love Karen and their daughter Becca. But boy is he fun to watch being bad!
10 of 18 Byron Cohen/NBC
Sarah (Yvonne Strahovski) from Chuck
There's no secret to why we love this agent. She's a gorgeous spy who pulls off every outfit from her Weinerlicious work clothes to a slinky red silk dress. And don't even get us started on that Princess Leia bikini. Meow!
11 of 18 Justin Stephens/Sci Fi
Sam Anders (Michael Trucco) from Battlestar Galactica
Sure, he's a Cylon, but if Starbuck can't stay away from his tall, tanned, cut bod and baby blue eyes, how could anyone else?
12 of 18 Mitchell Haaseth/NBC
Jim Halpert (John Krasinski) from The Office
He's adorable, smart, funny and exudes warmth and quiet sensuality. Plus his relationship with Pam is just so darn sweet and cute.
13 of 18 Mitchell Haaseth/NBC
Lyla Garrity (Minka Kelly) from Friday Night Lights This cast has lots of attractive girls, but Lyla's relationship with bad boy Tim Riggins makes her stand out. That, her doe-eyed, slightly naughty gaze and rocking body, of course.
14 of 18 Mitchell Haaseth/NBC
Chuck Bartowski (Zachary Levi) from Chuck
One part Zach Braff, one part babe. The combo is adorable, loveable perfection, both as Chuck the Nerd Herder and as walking spy computer. He makes us laugh, and we can take him home to Mom.
15 of 18 Andrew Eccles/The CW
Serena Van der Woodsen (Blake Lively) from Gossip GirlSerena has had a sordid past, but her long blonde hair, baby blues, and killer bod let her get away with a lot on the Upper East Side.
16 of 18 Virginia Sherwood/NBC
Tim Riggins (Taylor Kitsch) from Friday Night Lights
He's the classic bad boy. He drinks, he lives like a frat boy and sleeps around, but underneath it all, he's a real softy. A softy we just adore.
17 of 18 Brian Bowen Smith/The CW
Dean and Sam Winchester (Jensen Ackles and Jared Padelecki) from SupernaturalThis pair of brooding brothers are ruggedly handsome, but what sets them apart is their continual willingness to battle all sorts of ridiculous baddies. Everyone loves a hero, right?
18 of 18 Craig Blankenhorn/Fox
Peter Bishop (Joshua Jackson) from Fringe
He's a dry, funny wise ass. But to be fair, the main reason we like Peter so much is because we just love having Pacey back on television. Yay!
