Carrie Underwood gets sexed up for her upcoming appearance on How I Met Your Mother, where she plays a pharmaceutical sales rep and Ted's love interest!

Barney, who is left practically speechless when he hears she works in "the hottest profession" takes Ted back in time through the sexiest jobs ever, starting with prehistoric times, when Carrie dons a cavewoman outfit, to the 20th century, where she tends to an injured Barney as a nurse, then finally a sexy sixties flight attendant!

It's interesting to note that the only footage they released of Carrie's guest starring role is a clip in which she's got no lines. I mean none, nada, zip.

Does that mean Carrie can't act?
