Season 9: Episode 197: The One with Phoebe's Birthday Dinner
Phoebe plans a special dinner out for her birthday, and all the gang plans to come. However, only she and Joey make it on time. Monica and Chandler are late because they fight over the fact that he's started smoking again; and because she's ovulating and wants to conceive. Rachel and Ross are late because they lock themselves out of their apartment while Emma's inside; and their babysitter (Mrs. Geller) is late. Ross uses a lot of antiquated phrases, and Monica has the breasts of a greek goddess (according to Phoebe). Joey struggles with hunger, but in the end gets to eat everyone's food.
