Quote from Barney in The Fortress
Robin: We need to go into this marriage with a fresh start. What do you say we find a new place together?
Barney: I love you. And if that will make you happy, then let's do it. [they kiss] Wow, so we need to find an apartment where I haven't banged someone? How do you feel about Cleveland? [Robin chuckles] Nope. Ted's mom.
