Brian and Kate have their hands full at a slumber party with a guitar-strumming Ross, Eileen, two hyper kids, and another kid who's dreading the arrival of a new sibling.

When Kristin turns down his request for a date, Ross and his overactive teen hormones settle for an evening of team babysitting.

Buoyed by Ross's high aptitude scores, Kate goes to work as his high-pressure tutor.
