Quote from Robin in Baby Talk
Lily: You know, when you think about that, that phrase is really creepy. Marshall: No, it's not. It's fun. Here, watch this. Hey, Lily... Who's your daddy? Lily: [chuckles] 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.
