Barney: It just doesn't add up. How could Rhonda not remember me?
Ted: Well, maybe it wasn't that good for her. I mean, it was your first time.
Barney: Ted, it's me. I rocked her world. You don't believe me? Okay, story time. The year was 1998.
[flashback:]
Barney: [v.o.] I'd been going out with Shannon since freshman year of college. We were saving ourselves. So when we broke up there I was, 23 and still a virgin. I knew nothing about girls. So I went to the guy who knew everything about girls my brother James.
[present:]
Robin: Wait, your gay brother James?
Barney: Yeah, this was before he was gay.
