Ted: So Karen in New York, weird, right?
Lily: Ted, you cannot get back together with Karen.
Ted: I never said I was going to get back together with her. But I was thinking she's new in town, would it be the worst thing in the world if I gave her a call?
Marshall: No, Ted. It wouldn't be the worst thing in the world, it would be the fourth worst thing. Number 1, super volcano. Number 2, an asteroid hits the Earth. Number 3, all footage of Evel Knievel is lost. Number 4, Ted calls Karen. Number 5, Lily gets eaten by a shark.
Lily: I'm Lily and I approve the order of that list.
