Marshall has acquired a new tie with a duck pattern, which Barney despises because he finds the design unstylish. Now that Lily is pregnant, her breasts have gotten bigger, so Barney wants to see them; both Lily and Marshall refuse. The group decide to go to "Shinjitsu", a okonomiyaki restaurant for dinner, where Barney insults the cooking style, claiming he can do all the techniques the chef can do with ease. Marshall becomes angry and challenges Barney to do every technique, with permission to touch Lily's breasts if he succeeds. If Barney fails, he must wear Marshall's ducky tie for one year.
