ROFL! 
In addition to Bailey Quarters, I should mention a couple more.
Amy Allen from The A-Team.
Gina from Sesame Street.
bobkitty : that is too kind of you, but I would miss Cole too much. Perhaps we could work out a joint custody plan? 
There are many possiblities here, but my answer, hands down, is Paris Gellar, from Gilmore Girls. Had Paris actually gone to my high school, I would have mortgaged my soul for a date with her.
I don’t really know why.
- FCF
Dr. Luka Kovach, from ER
Constable Benton Fraser, from Due South
Oz, from Buffy the Vampire Slayer
Spike, from Buffy the Vampire Slayer
Angel, from Buffy the Vampire Slayer (not from Angel, though, because Angel’s best when he’s in love)
There are many, many more, but I don’t want to embarrass myself by admitting how much TV I actually watch.
Oh, come on, Edwardina, you are among friends! Regale us with your tales of wishful thinking. I’m about to go on a few more myself…
Gah, that’s what I loved about her! When she ended up in Coop’s room and they had a little teary-eyed conversation I thought I was going to murder him for not taking her right then and there in his special-agent arms…
sigh
Furthermore, for us Scully fans, two episodes kill me with her. The one is where they chase down a guy who can change his face (he was born with a tail) and he ends up impersonating Mulder and tries to hook up with Scully. I would love to sit back and have a series of mundane but somehow deep conversations with her over some red wine. MAN. (get giddy just thinking about it). The other one was a season or so ago, with the Millenium crossover/end-of-the-world stuff. They finished out the episode in a hospitol, watching the ball drop on TV. When it does, Fox leans in and kisses her, then says, “See? The world didn’t end.” So much meaning there! (more giddiness–SHEESH)
Ok, calm down. In addition to those previously mentioned, I would like to add:…
I, too, would love to date Buffy’s Willow Rosenberg, though pre-“I’m so addicted to witchcraft”. Back in season (3?) when Xander was still dating Cordie and they were sneaking kisses… my favorite Willow so far. And to have met the vamp Willow… oh geez.
I’d like to have a few dates with Samantha Carter from Stargate. She needs a good social life. I’d be happy to oblige.
Mention of Lisa from Newsradio… ah! Very nice. You got a little competition here!
Mary Ann from Gilligan’s Island. Sweet, honest, and good Lord what a looker.
Ellie Walker from The Andy Griffith Show. Pretty, intelligent, and able to handle any man with equanimity. She reminds me a lot of my wife.
Barbara (Valerie Bertinelli) on One Day at a Time, circa 1981. Now you know my terrible secret.
Sam Malone from Cheers. Grrrrrrrowl.
Angel from Buffy, back when he was mysterious, smoldering, tormented…and in shape.
That hunky guy from CSI. (Nick Stokes)
Jason Bolt from Here Comes the Brides. (Okay, I’m aging myself here.) He could sure swing an axe.
Good call. How can anyone forget the luminously lovely Mary Ann?
I will have to do somethinkin tonight, but offthe top of my head, especially since the Blake case is in the news is Rooster from Baretta.
In keeping with the Twin Peaks theme, I always wanted James, Laura’s ex and Donna’s piece on the side. Sweet, sensitive, mysterious, oohh my knees are giving out.
I have to second the mention of Ed Stevens. Ed’s always struck me as an adult version of Lloyd Dobbler, and that’s damn near perfect if you ask me.
A few more:
Josh Lymon
Jack McCoy, and of course, Mike Logan
I can’t believe nobody’s mentioned Mulder yet. Sure, he’s a little… um… out there, but the passion he has for the truth is a huge turn on!
My first two are still safe! Must grab more.
Marge Simpson. I love it when she wears her hair down. ALl those high school ones, whoa.
Adding to my list:
Liz Parker from Roswell. (The actress that plays her was born the same year as me. Bonus!)
Definitely a hottie, but seems like he’d be very high maintenance.
Sheri
I don’t know much about current TV in Anglophone nations, but I’d love to spend some intimate time with Seven of Nine from Voyager. Those guys keep screwing up with her, tripping over themselves and leaving her all by her lonesome in Engineering. But I request it be a long date. She is very bad-ass, and she gets away with wearing high heels. I’m sure they did that to pander to the pre-pubescent fantasies of young male viewers, but it still works for me.
Another…well there’s this newscaster in Japan named Yuko Ando. Do newscasters count? She is slick and savvy.
I guess I’m into the Robert Palmer Girl look.
Mindy - From “Mork and Mindy”
Julie, your nipply cruise director. (-:
Paget Brewster’s character in Andy Richter controls the universe.
Magnum PI - mmmmm!!!
Jean-Luc Picard
John Jr from NYPD Blue
Baldwin from NYPD Blue
The Rock from WWF - yes, he’s a character!!
As a pre-teen/young teen I wanted to date Ricky Schroeder on “Silver Spoons,” and I wanted to be Muffy Tepperman on “Square Pegs.”
A few years ago I wanted X-Files’ Fox Mulder and currently would go on a date - or anywhere else - with Buffy’s Spike.
