Kristen Bell has been killing it on the talk-show circuit recently. Following her adorable sloth story on Ellen, last night on Conan, the actress outlined her philosophy on a man's butt, or like she likes to call it, his cupcakes. In fact, according to Kristen, men and their butts fall into various categories. If you don't have cupcakes, you might have "flap-jack buns." Conan then made up his own classification for himself. Watch the two discuss this special part of the male anatomy — as Kristen explains, "behind is where you want to be."
