Lily: So guys, Marshall and I wanted to invite you to our place for a little couples' night.
Robin: Uh, sure. Why not?
Future Ted: [v.o.] For years, Marshall and Lily had been the only married couple in a group full of single people. It got lonely, so they were always searching for another couple to double-date. There was only one problem.
[flashback to Marshall and Lily getting ready to greet a couple in 2007:]
Lily: Welcome.
Marshall: Gouda?
Future Ted: [v.o.] They sucked at it.
Lily: This is great. We're having fun. You're having fun, right?
Marshall: So, should we just go ahead and lock the four of us in for new year's?
Man: Um, it's April.
Marshall: Right. Sorry. We're getting ahead of ourselves. Let's talk Thanksgiving.
Lily: Our parents really want to meet you!
