Quote from Barney in The Three Days Rule
Marshall: Yeah, but here's the real problem. Ted wasn't saying "I love you" as easily as we thought he would. Barney: Then we met... Stan. [flashback to Barney and Marshall laughing in the booth in MacLaren's:] Stan: Why are you making so much noise, man? [present:] Marshall: So we explained everything to him, and when we were done, something amazing happened. [flashback to Barney and Marshall sitting with Stan in the booth in MacLaren's:] Stan: Why don't you tell Ted that just knowing he's out there, thinking about you, caring about you, makes you feel safe? So, all your fears, all your yesterdays wash away, and only hope remains in the promise of his embrace.
