My post on the Best Authors thread made me once again realize my lust for Brian Greene, the superstring theorist. He’s just sooooo dreamy, and it’s more his brain than his body (though I’d take either— ftr, I’ve no idea whether or not he’s gay).
Who are some people you think are sexy as much (or more) for their minds as their appearances?
Very common. For instance, I’d love to mix it up with Dame Judy Dench, and it isn’t 'cuz of her cute skins or anything.
The World’s Sexiest Brains…
Yeah, you’re right… that would make a good slogan for the SDMB.
Anyhow, my nomination for World’s Sexiest Brain is Phoebe Juel, winner of the 1993 or so Jeopardy College Championship. Yowza!
Well thinking back a generation or so, Julie Newmar was really sexy and has a genius IQ (or so I’ve heard).
Jill St John also has a very high IQ.
This is right up my alley. Over the years I’ve had crushes on:
Jeff Goldblum
Kevin Spacey (I know, I know…)
David Duchovney
They all just seem so intelligent, and, curiously enough, they all remind me of my husband in some ways.
What a lucky gal am I. 
No thread of this nature would be complete without a mention of Carol Vorderman
IQ of 167 and a member of MENSA, according to IMDb
I’ve always had a serious crush on Jane Goodall.
What’s this? Another blonde hair. Doing a little more “research” with that Jane Goodall Tramp?
Just what I was going to say. Well, I better be off now, need to get some lunch, then its Beat the Nation followed by Countdown. Yay for daytime TV!
A story that made me like her all the more is when I read that her reps took major objection to the Gary Larson cartoon above and insisted he print an apology. She was in Africa at the time and when reached for comment she hadn’t heard of the cartoon. When she saw it she laughed out loud- she loved it.
The brain voiced by Kathleen Turner in The Man With Two Brains.
What?
Whoops, turns out Sissy Spacek did the voiceover. Still sexy.
Emma Thompson beauty, brains AND a sense of humor.
