Lily: Thank you, honey. I'm gonna get some great shots of our little group with this.
Future Ted: [v.o.] Now, kids, you've seen your Aunt Lily's photo albums: Leather bound, acid-free paper, adorable handwritten captions. And most importantly, the group shot. Cute photo, right, kids? But what you don't see is what happened 10 seconds before this picture was taken.
[flashback to 10 seconds before a Fourth of July picture was taken:]
Lily: Okay, I wanna get the perfect group shot. Marshall, sit between Robin and Barney.
Robin: What, why?
Lily: Oh, you know, light, color balance, aperture. You're just saying camera words. Wait. You don't want Barney and me to look like a couple in this picture, do you?
Lily: Of course I don't! You two aren't gonna last. I'm going for timeless here.
Barney: How dare you!
Robin: That is so rude!
Barney: It's true.
Robin: Totally true. We're running on fumes here. But still rude.
