I have a thing for redheads.
Can I add Emma Watson to the red-head fray? Redheads aren't my personal favorite, but then again, I'm not always correct... ;)
Skepchick and blogger Rebecca Watson does it for me. It's those glasses.
I'm going to go out on a really geeky limb and shout out my love for Patrick Steward as Captain Jean-Luc Picard.
The 9th & 10th Doctors of the new Doctor Who both has an awesome level of well over 9,000, but the 10th (David Tennant <3<3<3) wins for me.
And for the odder mentions, Garrus of Mass Effect along with Mordin Solus. I think the husband was actually jealous of a non-human videogame character for a while.
