Constantine Maroulis from American idol, who is actually pictured in Bill Maher’s latest book.
Jeff Corwin is adorable.
William Petersen from CSI pre-beard.
Eric Szmanda from CSI.
Adam Brody from the OC.
This might seem like an odd choice, but I love Mike Rowe from Dirty Jobs. He’s got a great sense of humor, not to mention being hot!
Are you seriously calling Cliff Clavin a obscure dude? I’m flabbergasted!
Me? I wouldn’t call it a crush…I’m madly in love with Krista Allen
Rachel True - Half & Half’s Mona
Amy Davidson, 8 Simple Rules’ Kerry
and Persia White - Girlfriends’ Lynn
I guess I like them biracial or redhead
For me, it’s all about Buffy’s Willow Rosenberg, the cute, brainy, redheaded, bisexual Jewish Wiccan played by Alyson Hannigan. I also dig Winifred “Fred” Burkle from Angel, played by Amy Acker.
Another vote for Willow! 
The guy who plays Sayid on Lost.
I’m a faithful viewer from the beginning, but I pay no attention to the credits so I don’t know any of these characters real names.
And I have never seen him anywhere but on the show, so I have no clue if he’s hot in real life. It may be just the shirtless sweaty version I see on the show that does it for me.
Claudia Black from Farscape
I forgot to include a link.
Susie Gharib from PBS’ Nightly Business Report.
Yep, that’s right, you heard me.
Caroline Ellis. You probably have NO idea who she is, but she was the lone female fairy in the Sid & Marty Kroft series “The Bugaloos”.
Here’s a decent picture: http://www.bugaloos.com/joy0.html
In my more twinkophile moments, the guy who played David (Johnny Galecki) on Roseanne is quite somebody I’d like to have scrubbed and sent to my chambers. Of course on the subject of twinks, the orgy possibilities of the last season of Boy Meets World are endless- I’m guessing that by then the core audience was 50% gay male.
Samp, how the heck do you come up with this inspired redneck homoerotica?
She has hair. Actually, another fearsome lady who used to present a financial show used to make me quiver: Consuelo Mack from WSJ Report. When she said “Have a good week and make it a productive one” at the end, I always felt she was speaking directly to me, who’d just finished another unproductive one.
He did other stufff? As far as I knew, he was the host of some show that no one else had ever heard of.
for me it didn’t matterthe character they played - it was the actor:
at various times over the last 25 years and for varying durations (in no particular order)
Scott Bakula
John Ritter
Alton Brown
Mike Farrell
John Corbett
Kelsey Grammar
David Hyde Pierce
Nicholas Brendon
Harry Anderson
Noah Wylie
Anthony Edwards
James Spader
the list goes on and on but I think that’s enough for now
Another dirty old man here.
I would definitely want to go to band camp with Alyson Hannigan. The most unrealistic aspect of “Buffy, The Vampire Slayer” wasn’t the vampire stuff, but the fact that Band Camp Girl was supposed to be the wallflower best friend while Sara Michelle Skeletor was the “hot” one.
Another TV wallflower I find hot is that little black doctor on "Gray’s Anatomy."Great eyes, great smile; I never was attracted to skinny model types anyway.
Among older women, definitely Kathy Bates from “6 Feet Under”. Actually, the Fisher Mom ain’t half bad in that one,either. "Daughter"Claire looked better in the earlier seasons when her face was chubby-cheeked( kinda gaunt this last season IMO).
On the"Sopranos", definitely Jackie Aprile’s widow.
James Lunday from In a Fix. He has those nice thick arms and a little pudge around the belly. The best episodes were when the crew pranked him and he had to change his shirt on camera. Oh, and he seemed to have a nice personality too. 
I think he may have had to go back Down Under.
And I can’t remember her name, but the Indian woman with the British accent who used to be on ITN News–I don’t see her in their correspondent roster.
Patrick Dempsey in *Grey’s Anatomy * is looking pretty good these days, continuing the attractive streak started in Lucky 7.
