Rachel is freaking out because her due date is one week and her and Ross haven't gotten any baby supplies yet. They go to a store and get A LOT of stuff, but Rachel is upset when the salesgirl flirts with Ross. Phoebe accuses her of being jealous. When the salesgirl stops by the apartment to ask out Ross, Rachel makes it apparent that she is not ok with it. When Ross returns from his date, she tells him that she doesn't want him to date because she wants him to be constantly available to her. Despite her being unreasonable, Ross agrees to put dating on hold to be there for her and the baby.
Meanwhile, Chandler is interviewing for a new job. Phoebe helps him practice his interview skills, encouraging him to fight his urge to constantly make jokes and come on too strong. She purposely practices by putting in the term "do-do," which Chandler has to sidestep without making an inappropriate joke. In the actual interview, the businessman talks about Chandler's "duties," but Chandler is able to resist making jokes. Afterwards, the man tells him to relax, and he mentions that he was really nervous and it was hard to resist the joke about "duties," which blows the interview.
