Marshall and Lily's wedding day has gone smoothly so far, but all good days have a glitch. While Robin and Ted are discussing something, Barney overhears them and makes it his duty to find out what they are hiding. Their secret goes from one thing to another. As they tell the story of their anniversary four weeks earlier, Barney is led to believe that they are engaged, that they broke up, that Ted is moving to Argentina with Robin, and that Robin is pregnant. Finally, Barney learns the real secret, that Ted and Robin have broken up. Meanwhile, Marshall and Lily haven't had one thing to eat at their own wedding. Both are starving, but Lily manages to find 4 strawberries, each in a champagne glass, and she winds up very drunk. Marshall and Lily then leave for their honeymoon, but make a quick stop for burgers, where Marshall hears an outsider refer to Lily as his wife. Ted informs Barney that he is his wingman again.
