Meanwhile, Jon was getting ready for school himself. He had decided to wish for something after he got ready for school, but now he changed his mind.
He walked back into his room and grabbed the stone. "I wish ..." he said, not realizing that the wish would be granted to his mom, instead of him "... that I had a foot-long dick."
When nothing happened, Jon tried again. "I wish my dick was bigger." Nothing. "I wish my dick was bigger!" he tried again, but there was still nothing. "I wish my cock was twice as long!"
His mother, therefore, was left with a foot long dick that got thicker with every new wish. But at least that last wish didn't affect her, since wishes still couldn't be reversed. After a wish for a foot-long dick, that last wish couldn't lengthen it further - since if it did, it would no longer be a foot long, contradicting the first wish. However, the two wishes before the last wish could be granted, since they had nothing to do with length.
