I'd toss in a vote for snl's Tina Fey or maybe The Sarah Silverman Program's Sarah Silverman... But that's my laughter-lust playing on me...
Part of me says a younger Sandra Bullok back when she did "Demolition Man" with Slurvester Slurlone... that same part is all into Sabrina Lloyd who i doubt anyone knows, was on a short lived sci-fi show called "Sliders" with Jerry O'Connel (who by the way rules at doing shows & being cheesy--ever seen "My Secret Identity"?)... maybe that's just sciencefictish fascination...
I cannot believe no one suggested a young Julia Roberts.--hey if they get to pick a dead guy with a big hole in his head from when he wasn't dead & had less holes in his head, it's fair to pick folks when they were younger...
But my actual vote would go, not because i find her to be THAT sexy, tho i do find her sexy, more because she seems to - as others have said - ooze sexuality - tho not in any disturbing or graphic way-- To this obscure young actress who was briefly on soap operas named Allison Hirschlag... but not on set--that make up looks... well, disturbing... The reason i know what she looks like without the streetwalker-style-soap-opera make-up is i saw her do some stage acting around the same time, & everyone's reaction to this girls looks was as if they'd been told "Simon says drool" .. anyway her or Kelly rrrrrRipa.. but that could be comedic attraction again...
Edit; Of course I'm attracted to women. Why else do you think I act like such a kranly kran?.. [cause you know krans are all androgenous & my name on forums always has the 'ann' part.... --it's all a ploy..]
