We may not know a McDreamy from a McNugget, but when it comes to TV doctors, there is only one who makes our body temperature rise. The pulse-quickening internist played by Olivia Wilde on House, M.D. is named Thirteen (which we presume is out of 10) and has a terminal illness that causes her to dabble in drugs and casual sex. (That's how we want to go!) But we were drooling over this N.Y.C. native long before she was injected into Fox's hit medical drama. Roles on small-screen faves The Black Donnellys and The O.C. introduced Olivia to the world, but it's her prehistoric part in this month's Year One that will put her on top of it. As the object of Cro-Magnon lust in the Judd Apatow-produced, Harold Ramis-directed, Jack Black-starring comedy, Olivia will surely knock moviegoers back to the Stone Age. Ugh!
