The One Where Chandler Takes a Bath

Ross and Rachel discuss possible names for the baby, and then argue over whether they should find out the sex of the baby. Monica talks Chandler into taking a bubble bath, and he likes it so much that he starts taking them all the time. Joey tries to have a serious conversation about "the rules" with Chandler and Monica, which makes them think that he wants to do what they did... with Phoebe.
