Quote from Phoebe in The One with the Red Sweater
Monica: Hey, how are you feeling? Got any morning sickness? Rachel: Ssh. The guys don't know, do they? Monica: No. Joey and Ross don't know anything and Chandler still thinks Phoebe's pregnant. Phoebe: Hey, that's right. Chandler does still think I'm pregnant. He hasn't asked me how I'm feeling, or offered to carry my bags. Boy, I feel bad for the woman who ends up with him. After you, of course.
