Marshall: Ted's in love with Zoey? But, but she's married. That boy needs an intervention.

Barney: Does anyone know why we're here?
Lily: Yeah, who called this intervention?
Ted: I did. It's for me.
Lily: This is about the coffee breath. Finally.
Robin: Hmm, no, it's the shoulder hair.
Barney: Guys, just let the man explain how it's all about his wearing a lady's watch.
Ted: It's because I'm in love with Zoey, and she's married, so it needs to stop. And... intervene.
