The 20-year-old country-pop sensation couldn't have been more composed during her first visit to Letterman's couch (she had previously appeared only as a musical guest.). Even after Dave paid her what she politely termed "the most unique compliment I've ever gotten" — "You smell like expensive wood" — she didn't bat an eyelash, agreeing that her upbringing on a Pennsylvania Christmas-tree farm might explain her scent. I guess after your VMAs speech has been hijacked by Kanye West, nothing throws you anymore.
Swift also deftly deflected a question about her penchant for writing songs about ex-boyfriends like John Mayer: "This is the third album I've done this, so they've had fair warning." The girl even spoke Japanese! In a word, she was saikou (awesome).
