The Duel

As Lily becomes more of a permanent fixture in the apartment, Ted feels like he is being edged out of the mix by his engaged roomies. Petrified of being left alone and homeless, Ted tells Marshall that when he and Lily are married, he wants the apartment. The problem is that Marshall wants to keep the place, too, so they settle it like real "grown-ups" -- launching into a sword fight that leaves one man down for the count.
