Quote from Chandler in The One Where Ross Is Fine
Monica: Hey, Pheebs. Phoebe: Hey. Monica: We just want to give you a heads up. Bill and Colleen hate us. Chandler: Owen didn't know he's adopted and Monica told him. Monica: What? Phoebe: Still, he had to find out sometime. Chandler: Yeah, but how would you like it if someone told the triplets that you gave birth to them? [the triplets look at Chandler] I'm gonna go tell Emma she was an accident.
