Robin: What are you doing here, Lily?
Lily: I've been using Barney's apartment to pump milk for Marvin.
Robin: What?! Why?
Lily: Our apartment is so crowded these days, I don't get a minute to myself! I have a key to Barney's apartment, he has a kick-ass couch, and he DVR's all the Real Housewives shows, including the reunion specials.
