Quote from Robin in Duel Citizenship
Robin: Barney, I've thought about this. When you stood up and told off those people, I thought, "Yeah, America's cool." Barney: Hmm. Robin: And then when those guys pounded the stuffing out of you, I thought, "Yeah, Canada's pretty cool, too." I may have taken a few pokes myself. So, I've decided, dual citizenship. I'm going to be American and Canadian. Barney: Wait, you can do that? Robin: Yeah, dummy. Instead of being a woman with no country, I'm going to be a woman with two. Barney: I see. Robin: You understand? Barney: No, I can see out of my left eye again.
