Quote from Marshall in Rabbit or Duck
Marshall: We got her. It's the craziest thing. We were searching all week, and then, a couple of hours ago... [flashback to Marshall and Lily at MacLaren's:] Marshall: Trudy? Lily: Married. Marshall: Blah, blah? Lily: Committed. Marshall: Relationship? Lily: Bellevue. Marshall: Natalie? Lily: Ted's her least favorite person in the world. Marshall: Well, she's not getting any younger.
