Karyn looked round the room. Nothing, it seemed, had changed. She looked at Jon, but he was the same, and at herself, no change there.
"I give up. What did you do?"
"I'm not telling. Do you want a clue?"
"Okay, then"
"It's something I did to you," said Jon.
"To me?" Karyn looked at herself in the mirror in Jon's room. She could not see anything different. "I give up"
Jon was trying to conceal his laughter. "Nothing different about your bottom half?"
"Nope"
Jon looked at Karyn. He had taken Karyn's bottom half and turned it around, so that her bottom was where her vagina was and vice versa. Her legs faced the other way, so when she sat, she was facing the opposite way. Her feel now pointed backwards instead of forwards. Karyn stamped her foot, and Jon laughed at the bizarre sight of her back to front leg stamping.
Karyn ran up to Jon. "WHAT DID YOU DO?"
