Carol: This wouldn't have anything to do with the fact that he's being raised by two women? Ross: You know what? It's fine. If you're okay with the Barbie thing, so am l. [later:] Ross: Give Daddy the Barbie. Give me the Barbie. Don't you wanna play with a monster truck? No? Okay. How about a Dino-Soldier?
