Jon let out a little chuckle, the other person need not be a person at all, now THAT would be proper punishment for sarah.
He grabbed the stone and said. "I wish Sarah Macmillain would swap personalities with a monkey for a week and think it was some kind of scientific test"
Meanwhile Sarah wound herself strapped down to a machine with a doctor standing over her.
"don't worry, the experiment won't hurt at all after the initial jolt. yoyu won't even notice the swap." the doctor said.
"who are you going to swap me with" sarah asked.
"not who, what." the doctor replied, he gestured over to his assistant wheeling over a chair with a screeching monkey tied down on it.
"WHAT!" Sarah yelled, "I don't want to be swapped with a smelly ape."
"now, now dear calm down" The doctor said.
"CALM DOWN! why would i calm down, your making me act like a monkey!"
"I weren't talking to you" the doctor said, "I was talking to Lucy, she's my favorite research monkey."
He then flipped a switch and sarah felt a jolt go through her.
