In Lou's fantasy sequence, taking place 50 years into the future, the elderly Mary receives a post cart card from Rhoda, in which Rhoda states she is still waiting for Joe to come home (referring to the separation storyline on Rhoda).
The short nightgown Mary wears in Ted's fantasy sequence is the same nighty Rhoda gave Mary when she went in to the hospital to have her tonsil removed (ep. 20, "Hi!"). This nighty had appeared in a handful of episodes since then, but here it would make its final appearance.
