Lily: Wait a minute. What happened to that girl Cassie?
Ted: Cassie?
Future Ted: [v.o.] Cassie was the girl I'd spent the entire previous night consoling. Just consoling.
Ted: Yeah, that's not happening.
Future Ted: And then, in her anger, Lily gave me a piece of advice about which she would later say...
[flash-forward:]
Lily: Oh, doggy, that was some bad advice.
[present:]
Lily: Okay, here's why you're an idiot. Did you find Cassie attractive?
Ted: I guess.
Lily: Is she a relatively normal height?
Ted: Yeah.
Lily: So end up with her already. God, do you really think that you're gonna find some perfect girl who checks off every item on your list?
Ted: Well, not every item. I mean, she doesn't have to share my love for coins. Although it would be nice, just once, not to have to go stag to Coin-Con.
