Quote from Barney in Little Boys
Barney: It gets better. Remember Ted's phone conversation? [flashback to Ted talking to Stacy on the phone:] Ted: Well, have fun in yoga [present:] Barney: Well? [flashback to Stacy leaving yoga class:] Barney: Oh. Stacy: I'm sorry. Barney: Stacy, right? Stacy: Yeah. Oh, you're Ted's friend from the bar? Barney: Yeah, wait, don't tell me you go to yoga here too? Stacy: I do.
