Quote from Barney in Last Forever
[Barney and Robin in Argentina in 2016:] Robin: I know I'm always traveling. We both hate it when I'm gone, we both hate it when I drag you with me. Neither of us is happy. Is this just not working anymore? Barney: Wait. What "this"? This-this? Robin: If I gave you an out, right now... If there was an exit ramp right here at the three-year mark, would you take it? Barney: Before I answer that, real quick: you want to get super drunk and have sex right now? Robin: Of course.
