Plot
Marshall and Lily's wedding reception is in full swing, but they cannot eat there because food is being taken right out from under them while relatives congratulating them just before they can get a bite. Lily also gets drunk, and misses in her attempt to feed Marshall some cake. When they finally get to the limo to their honeymoon, which is driven by Ranjit, Marshall asks to stop at a fast-food restaurant so that they can get something to eat. At the restaurant, Marshall begins to fully realize that Lily is his wife, and his realization makes him very happy.
At the reception, Ted and Robin begin discussing a big announcement, and when Barney overhears, he harasses them until they relent, telling him of what happened 2–3 weeks before the wedding.
