Future Ted: [v.o.] The next night, I was still angry at your aunt Lily. Until...
Karen: Hi.
Ted: Hi. What are you...
Karen: Lily came by and explained everything. And she gave me this note for you.
Lily: [on the note] "Ted, I'm sorry. It doesn't matter to me who you marry. I know they'll be awesome because they'll think you are. To show I mean it, I put together a little surprise for you and Karen upstairs. Love, Lily."
Marshall: [on the note] "P.S. Sorry the envelope was already open. I had to read what she wrote. Marshall."
Karen: Sabotaging our relationship? I got to say, even using the specially-ordered extra-low bar by which I judge your friends, Lily really outdid herself this time. Obviously, we can't ever see her again. I know. It's a big loss, right?
[fantasy scene of Ted and Karen on the front porch:]
Karen: Hey, remember your old college roommate? He was married to that shrill little idiot girl.
Ted: Marshall. Oh, it's been so long.
Karen: God, I hated him. Anyway, here's his obituary.
