Quote from Lily in Baby Talk
Marshall: Let's make a baby! Lily: Whoa! Baby, you're packing snowballs, and your breath smells like a mermaid fart. Marshall: Loving the dirty talk... But you know what's even hotter? If we face this-a-way. Ooh, we're bad. Lily: Wait... hey, baby, why are you facing me north? [gasps] 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? You're trying to make us have a girl!
