Quote from Phoebe in The One Where Chandler Takes a Bath
Phoebe: Are you going to find out the sex of the baby? Ross: No, no. We talked about it and we don't wanna know. All we care about is it's happy and healthy. Rachel: Yep, happy and healthy. And cute. Ross: Smart. Rachel: Popular. Ross: With an aptitude for science. Phoebe: Are you two talking about the same baby?
