Quote from Monica in The One Where Rachel Tells...
Rachel: And I also I wanted you guys to know I am telling the father today. What? What? What? Joey: We know it's Ross. Rachel: How? How do you know? Phoebe: It was his sweater. But, oh, my God. Rachel: I so I wanted Ross to know first, but I'm relieved you guys know. Monica: This is so great. I'm gonna be your baby's aunt. Rachel: I know. Phoebe: Me too. Joey: I'm gonna be an uncle. Come here. Rachel: You'll all going to be aunts and uncles. Monica: Yeah, but I'm the only one related by blood.
