Speaker 2: Oh, oh my God! I can practically hear the mahjong tiles! 
Speaker 3: Okay! All your tests look fine. Now, are you two interested in knowing the sex of the baby? 
Speaker 1: Uh, no. No, we're not. 
Speaker 2: But you have it right there in that file? You could tell us whether it's a boy or a girl? Dayton or Sandrine? Phoebe or Phoebo? 
Speaker 3: That's right. But if you don't want to know... 
Speaker 1: No, no, we want to wait, right? 
Speaker 2: Right. Right. 
Speaker 3: Oh, I'll be right back. And, uh, I know it's really not my place, but please don't name your child Phoebo.
