Quote from Ted in The End of the Aisle
Ted: First off, kudos to Marshall and Lily for calming you down. Second, do you... Do you remember Robin's locket? Barney: Yeah, of course. She never found it. Whoa. How did you...? Ted: I never told you about it because I was afraid you'd take it the wrong way, but I actually wound up tracking it down. It's a long story. I was gonna give it to Robin as a surprise, but... she needs it to come from you. Barney: Ted, I don't know. Ted: Take it. Please. Barney: How'd you find it? Ted: I didn't find it. You found it.
