Ross' ex-wife, Carol (Jane Sibbett), goes into labor, leading to a heated "I'm more help to her!" confrontation between Ross (David Schwimmer) and Carol's girlfriend, Susan (Jessica Hecht). In her efforts to end the argument, Phoebe (Lisa Kudrow) performs a reverse procedure of sorts by dragging Susan back into the closet. Meanwhile, Rachel (Jennifer Aniston) learns more than she wants to about the OB-GYN (Jonathan Silverman) she likes, Joey (Matt LeBlanc) assists in another birth, and Monica (Courteney Cox) broods and broods. June Gable, normally cast as Joey's agent, Estelle, is here seen as a nurse. ~ Hal Erickson, Rovi
