Mary Lynn Rajskub
or, perhaps more accurately, Chloe O'Brien.

She is by no means conventionally good-looking but as she is a super-geek-government-hacker type, I suspect I am not the only one to have developed an attraction. I've watched every episode of 24 (I'm currently re-watching season 7) and Chloe's combination of hard-to-get, cold shouldered demeanour; sneaky underhanded counter-terrorist activities and witty repartees have me hooked.

Continuing on in the same vein, Janeane Garofalo is also a bit of a hottie, for identical reasons, at least as far as 24 Season 7 goes.

***In an attempt to placate the 'Let's not just make a list' crew, I've tried to answer the question as fully and accurately as possible but it's hard when the question is essentially 'name a person that you fancy'.

/my two cents

Janeane Garofalo as The Bowler
floats my boat.

I would've done her
right up until her aborted standup gig at Latitude Festival in 2009. She was shite and went off in a flounce because we weren't rolling about at every syllable.

Ed Byrne came on early and filled her slot (fnarr fnarr etc.) and his own.

Now I'd rather do him.

I had no idea that she was a comedienne.

Yep.
As is Mary Lynn.

Never heard of her,
but google shows she has a very odd face.
