Quote from Barney in Do I Know You?
Lily: Barney, you're going to have to stop screwing around if you want to be Robin's boyfriend.
Barney: Whoa, whoa, whoa. "Boyfriend"? I don't want to be Robin's boyfriend.
Lily: Well, what do you want, then?
Barney: I don't know. I just want to be with her. All the time. I want to hear about her day and tell her about mine. I want to hold her hand and smell her hair. [scoffs] But I don't want to be her stupid boyfriend.
Lily: Barney, what you just described is a relationship between a boyfriend and a girlfriend. And a pretty clingy one at that.
