Quote from Ted in Oh Honey
Marshall: Ted's in love with Zoey? But, but she's married. That boy needs an intervention. Robin: Funny you should say that. [flashback:] 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.
