It's party time for Bill and the group. For Dave, it's a blowout thrown by a female coworker he has his eye on, but pre-party hunger pangs do him in. Jonathan invites everyone to celebrate his birthday---by standing in line for hours for frozen yogurt. Inger and the feuding Darlene and Michael show up. And Bill throws a raucous, if boring, beer bash at Anne's house to impress a woman he's afraid to ask out.
