Quote from Ted in The Ducky Tie
[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.
