We know this happened on Friday, but we've just now recovered from a rather raucous Halloween. Plus, who doesn't love a good dose of Mary-Kate before noon? The Olsen spent her All Hallow's Eve on Conan O'Brien's couch playing dumb when asked about boho-chic, "Oh, that's just laziness I guess," and talking about whether or not she can tell herself apart from Ashley in pictures. Things get interesting about five minutes in when Conan asks MK for fashion advice and the host strips down to his very pale tummy. If we had MK at our disposal, we might ask her for style advice, too. But even she couldn't get us to strip down on national TV.
