Toward the bathroom!

Nancy, concerned about the crowd outside, pulled herself all the way into the room. She didn't have much time. Lauren just looked up at her in disgusted shock. With her hands over her rear, Nancy ran through the door, out of the room, into a long hallway. Trying door handles left and right, she found most of them locked. "Which one is the bathroom?!" she shouted, to no one but herself.

Then, success, one of the door handles turned!

Her heart dropped to her stomach when she saw sunlight coming through the partially opened door. She had exited into the driveway! This was no good, she needed a bathroom. As she turned back to look for the bathroom, her eyes picked up a red Bugatti, bearing the vanity license plate "CHRLOT."

In spite of her urgency and pain, a smile creeped across her face, as she walked closer to the car. It was a stroke of luck that the moon roof was open. Putting her knee on the hood, she hoisted herself onto the car and plopped her nude bottom right on the moon roof. She didn't have to wait any longer for relief, so she let go.

That's when she heard a loud beep. Moments later, she was still sitting there, not yet finished, and the car alarm, in full blast, had brought all the partygoers to the driveway. Charlotte was cursing with tears in her eyes, and Claudine was screaming about her Gucci jacket she had left on the passenger's seat. Everyone else thought it was hilarious, except for Lauren, who was still sitting in shock on the floor of her bedroom, covered in puke.

Nancy had been thoroughly humiliated, and though she couldn't humiliate her rivals in the same way, she was able to ruin their day by turning around the very prank they had played on her, which had been part of her original plan for dealing with Charlotte.
