Barney : "I'm a magician, Robin. Misdirection and deceit are my stock in trade. You don't want me to lie to you? Lies are the reason that we're together. Everything single thing I did to get you to say yes to me on that rooftop-Patrice, the false engagement, everything-it was all utter malarkey. But underneath all of those lies is one true thing. One true thing that can support the weight of all the lies in the world, and that's the fact that I love you."
