Tuesday Weld as Thalia Menninger on The Many Loves of Dobie Gillis.
Agent 99
Laura Petrie
Dinah Shore
Michael J. Fox, in absolutely anything he was in, but of course mostly as Alex. 
First time I remember cutting out pictures from teen magazines and actually kissing them.
Judy Carne and Goldie Hawn from Laugh-in
Valerie Bertinelli from One Day at A Time
Karen Valentine from Room 222
About every guest female from Love American Style
Laurie Walters (Joannie Bradford) from Eight is Enough. Whatever you didn’t see of her on TV you could see in The Harrad Experiment.
Charo
Yvonne Craig (Barbara Gordon/Batgirl)
A friend of mine has a 10 minute monologue written on how TV SciFi made sure he grew up heterosexual.
Erin Grey in Buck Rogers, but NOT Silver Spoons (I hated that Ricky kid coz I knew too many like him AND he was that much closer to Erin Grey than I ever would be)
Bailey from WKRP
Mr. Kotter’s wife
I think the last ones were Minerva Mink from Animaniacs and Catwoman from the Batman cartoon in the early 90s. Oh, my golly, those cartoons were not made for kids…or else I was REALLY lonely.
Justine Bateman and Valerie Bertinelli.
David Duchovny from *X-Files * and George Clooney on ER.
And I’m only slightly embarassed to admit I was in college when I had a crush on Joshua Jackson from Dawson’s Creek.
Ross Martin as Artemus Gordon. Just way cooler and more…interesting than Jim West could ever be. Probably helped seeing him as Baron Von Schtupp in “The Great Race” numerous times on TV as well.
The woman who played Morticia on the Addams Family.
Julie Newmar (Catwoman)
Ginger & Mary Ann
Agent 99 (who I used to think was the same lady as Ginger (I was like 5, ok?))
Daisy Duke
Wilma Deering (Buck Rogers)
Tracy Gold from Growing Pains
Emma Samms from General Hospital
No, it wasn’t Jimmy (brother of Kristy) McNichol, but Philip (brother of Nancy) McKeon.
As for me: Echoes of the Maureen (Marcia Brady) McCormick, Valerie (Barbara Cooper) Bertinelli, and Farrah when she was still Fawcett-Majors nominations. Even before Charlie’s Angels, I was aware of Farrah from Noxzema commercials (link is a YouTube video) and an episode of Apple’s Way.
Also the Bradley girls (especially Lori “Bobbie Jo” Saunders) from reruns of Petticoat Junction.
Another vote for Valerie Bertinelli here
No, no, no. Billie Jo (Meredith McRae)
No love for Samantha Stevens? Or her wicked sister (cousin?) Serena?
Maryann, from the Island, certainly.
Angela Cartwright from Lost in Space. Sigh.
You guys know *nothing.*Holly (Katie Coleman) from Land of the Lostis the only truly beautiful little kid love.
My T.V. lusts at all ages are ,Jennifer Aniston
Willow from Buffy
A female officer with an impressive rack in Babylon 5
Emma Peel from the Avengers
And one time rather worryingly when she was wearing a very tight sweater the mum in Malcom in the Middle.
I’ll second those who mentioned Fred Savage from The Wonder Years and Marc-Paul Gosselaar from Saved by the Bell. Always had a weak spot for cute and nice.
But my main crush was Johnny Depp in 21 Jump Street. He’s still on the top of my list so I guess you can say we’ve grown up together in a way. 
Me too! And here I was thinking I was the only one. Other crushes of mine included Zak from Saved by the Bell, David Duchovny, and William Ryker
Only one and a half votes for the pink power ranger?!
I’m not sure I’ll be resubscribing next year, it’s just, I can’t fathom this.
And I hope you’re talking about the original one (Amy Jo Johnson) and not that bitch with the British accent that came after her.
When I learned she did a brief topless shot in a movie I couldn’t netflix that movie fast enough and mas… something like a motherfuck.
That reminds me, I need to go back and check on a Holly Hunter-related thread.
Pink Power Ranger: case closed.
(oh, and Angua, “Call me Will.”)
I was stricken by Lt. Ellis on UFO: purple hair, form fitting outfit, huge eyes, eye makeup applied with a trowel – what’s not to like? (And does Lt. Ellis look like a living precursor for every anime cutie ever, or what?)
(Check out one of the closeups of Lt. Ellis and the shot of her changing clothes in IDENTIFIED from the character photos page if this link doesn’t work)

I was also quite stricken by Skydiver Operative Georgina Moon, but I think it was mostly the uniform. Mostly.
