[flashback to Ted running into Victoria at an event:]
Victoria: Oh. I'm really happy for you guys. You look cute together.
Ted: Oh, no, no, we're not together. I mean, we-we dated for, like, a year. But now we're just friends. It's not weird.
Victoria: No, no. Why would that be weird? I mean, if you hung out every day, that would...
Ted: We do.
Victoria: ...still not be weird. Boy, I've never known anybody that hangs out with their ex every day.
Ted: Well, Barney does.
Victoria: Really? Who's Barney's ex-girlfriend?
Ted: Robin.
Victoria: Your Robin?
Ted: Mine and Barney's, yeah.
Victoria: You don't all three hang out together?
Ted: All the time.
Victoria: And we have weird.
