I remember a premise to a TV Show episode, but I don't remember the show?

It was about someone having a slumber party, but when they got up in
the middle of the night to go to the bathroom, there were so many
people on the floor that they couldn't walk without stepping on
someone. I'm pretty sure it's either Lizzie McGuire, That's So Raven,
or one of those live action clips at the end of Cyberchase.
