Ben always cries when he's near Monica. Ross has an allergic reaction to Monica's Kiwi Lime Pie; his tongue swells up and he has to go to the hospital. Chandler and Joey take care of Ben for the day, but accidentally leave him on a city bus while meeting women. They retrieve him from Human Services, but are a little unsure whether they've got the right baby. Phoebe is displaced when Terry, the manager of Central Perk, hires Stephanie, a professional singer, to play at the coffee house. Rachel arranges for Phoebe to play after Stephanie, but Phoebe feels slighted because, unlike Stephanie, she won't be getting paid. She becomes a street musician, outside Central Perk.
