Future Ted: [v.o.] Kids, when Lily and Marshall started trying to have a baby, they went a little crazy.
Lily: We've been trying and trying, and still nothing's happened. I'm just worried we can't have children.
Doctor: And how long have you been trying?
Lily: Six days.
Future Ted: [v.o.] But then, months went by, and still nothing happened.
Lily: Something must be wrong. We're doing it, a lot.
Marshall: And everywhere. The kitchen, the bathroom, the living room, outside in your wait... The kitchen.
Lily: Seriously, Doc, why isn't this happening?
