Quote from Barney in Duel Citizenship
Robin: Well, there's only one possible way to avoid getting deported. My lawyer said I could become an American citizen. Barney: Perfect. Problem solved. Welcome aboard. Robin: Well, it's not that simple. I'm a Canadian. I was born there. My family's there. It's who I am. Barney: I know, and it's provided us with a lot of laughs. But, Robin, if you want to live here, work here and throw chairs at people here, you have to do this.
