Quote from Lily in The Sexless Innkeeper
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!
