Quote from Barney in The Possimpible
Barney: I can't believe you might be kicked out of the country. Robin: God, I know. My whole life is here. Ted: No, we won't let this happen. I mean, one of us will help you find a job. Lily: I bet I can get you something at my school. Marshall: No, guys, it doesn't work that way. Robin only gets her work visa if she gets a job in her field. I mean, you know what? I guess you could stay if you married a U.S. citizen. [Barney stands up, gets down on one knee behind Robin] Yeah, that could work. Oh, They could never process that and make it official in time. That won't work. [Barney stands up and returns to his seat]
