Freaky Friday (on a Saturday)

A wicked thought crossed Josh's mind. If he could swap into other people's bodies what would happen if he swapped into someone's body whilst he wasn't in his original form?

He grabbed his mother's laundry hamper and made his way into the laundry room, the perfect place to test out his new hypothesis. He shut the door behind him and locked it, he didn't want to be disturbed right now.

He opened the dryer and began pulling out clothing and sorting it into various piles. He was in luck, by the time he'd finished he had enough clothes to swap with either sister and enough of his own clothes to swap back if he wanted to. Now the only question was, which sister did he want to swap with?
