Quote from Barney in The Bro Mitzvah
Barney: [answers phone] Hey, Robin. Robin: Did you tell your mother I'm a virgin? Barney: What? Why would you think that? [flashback:] Loretta: Save yourself room for dessert. And I hear you excel at saving yourself. [flashback:] Loretta: You are so funny. What's gotten into you? Oh, that's right... nothing ever. [flashback:] Loretta: You may be nervous as to what goes where on your wedding night. It's really simple. Let me show you. And let's start with the fundamentals. [present:] Robin: Why would you tell her I'm a virgin? Barney: I panicked. Look, I really want her to like you, so just go with it, okay? Okay! Robin: Listen, Wuv-Wuv, you better get your ass back... [Barney hangs up]
