Lily goes through Ted's list of things he wants to do in New York before he leaves for Chicago, and discovers that he and Marshall accidentally ripped up her rehearsal dinner dress while dueling with their swords one last time. As punishment, Ted is forced to wear a 1920s bathing costume, and Marshall, still en route to the wedding, must forsake his Minnesota Vikings gear to don Green Bay Packers clothing. Despite the fun and games, Lily is troubled by the thought of Ted moving, and the fact that she's the only one who knows about it. Robin and Barney realize they have very little time together before their aging relatives descend on them for the wedding, and so try to find time to be intimate, which proves difficult.
