Bill and Hillary are fast asleep in the First Bedroom, when Hillary wakes and starts shaking Bill.
Bill groggily opens his eyes and says, "Honey, it's 3am. What do you want?"
"I have to go use the bathroom," Hillary replies.
Bill blinks. "Please tell me you didn't wake me up just to tell me you have to go to the bathroom."
"No," Hillary says, "I just wanted to tell you to save my spot."
