Future Ted: [v.o.] While Lily was dropping the ball as maid of honor, the best man was busy knocking it out of the park.
Barney: [hisses] Hey, buddy, listen. My Great Aunt Ida has corns on her feet and needs a first-floor room. Uh, would you mind switching rooms...?
Ted: Say no more. The best man is on it.
Barney: Thanks, Ted.
[later, Ted is in a grim, windowless basement room where he sits down on a fold-away bed. It folds up on him. The sprinklers then go off.]
