Marshall: So, have you guys landed on a name yet?
Stuart: We're trying, but it's tougher than you think. You see, I like "Tiffany."
Claudia: And I don't want my daughter to have a whore's name.
Stuart: That's my mother's name.
Claudia: I know.
Stuart: Oh, I got it. How 'bout we name the baby after you... "Frigid Shrew."
Claudia: Oh, that's good. No, no, no, no. Let's call her "Vodka." Then at least we know you'd hold her tight and never let her go!
Stuart: Don't knock the vodka. Wouldn't have a kid without it.
Robin: Don't you guys ever watch my show?
Marshall: Oh, honey, I really try. Our DVR won't recognize it as a television program.
Marshall: Hey, Lily... Who's your daddy?
Robin: Okay, uh, let me get this straight. So, in, uh, in this scenario, because you make such sweet love to Lily, she is now your daughter.
Marshall: No, she is not my daughter. I'm just her daddy.
Ted: Wow. That is disgusting.
Lily: Why are you facing me north? You're trying to make us have a boy.
Marshall: I... can ex... How do you know about the north thing?
Lily: Um, um...
Marshall: And what are you doing with those lemons?
(Marshall remembers his father)
Marvin Eriksen Sr.: Baby girl fertilizer!
Marshall: You're trying to make us have a girl!
Marshall: How come whenever there's a creepy kid in a horror movie, it's always a little girl, or twin girls who speak in unison?
This is a reference to the 1980 Stanley Kubrick film The Shining.
When Marshall suggests naming their baby Rob, Lily remembers a kid named Rob in her kindergarten class, who touched her breast. This is the story of why Lily had purple fingerpaint on her shirt in the pilot episode.
