You've gotta be kidding me!

Chip of the old block came home from a birthday party yesterday. We told him to wash his face paint off prior to retiring to bed. He hops into the bathroom to 'unmake' his face and closes the door behind him. His sister had already completed her deconstruction and we hear from behind the closed door, "You've gotta be kidding me!"

His sister says, "You need to use soap AND water."

"You mean I need soap?"

Duh.
