So, we used to have Harry Potter day at camp. Everyone dresses up, and someone is Voldemort and you have to go to stations to get ingredients for the potion to kill him. One time, "Voldemort" had to pee, so he went across the field to the port-a-potty and the kids saw and chased him cause they're always chasing him and screaming "Wingardium leviosa!" So he went into the stall, but part of his cape got stuck in the door and the kids were pulling on it and yelling at him.
And he opened the door and said "THE DARK LORD NEEDS TO PEE!"
Even super evil villains have bodily needs.
