A strange idea entered Mikey's mind. Might as well try it, he thought, I can just reverse it later.
His mind drifted to Sarah McMillan, the sexy cheerleader from Jon's school. "I wish that, over the next week, Jon's personality and memories would gradually change until they are identical to Sarah McMillan's. He will begin to act like her, think like her, and even dress like her."
Mikey chuckled at his wish. He couldn't wait to see his brother parading around in a cheerleader's outfit. He wondered what Sarah... the real Sarah, would think.
