Kyle glanced around the room, looking for someone to swap with. His current life didn't understand math at all, and he was getting sick of wearing a skirt and having this curly hair fall in his face, so he tried to aim for one of the guy classmates. He found one normal looking guy who was reading from his math book.
Kyle tried to aim as nonchalantly as possible, but in those efforts, accidentally selected the matchbook instead. Kyle then selected himself and hit swap. He felt reality shift again, but this time he didn't move seats. He was confused as it appeared that his clothes changed from a cheerleader's outfit into that of a dorky sweater vest with jeans. He realized he had glasses on, felt some zits on his face, and realized his curly hair was now longer and in pigtails.
Looking down at his work, he noticed it was all completed. Looking at every question was now so much easier as he understood it all. He looked back at the boy and saw he was normal, but the boy he was now sneakily reading was on hot cheerleaders weekly. Kyle figured he had swapped with a book instead of the kid. Apparently swapping wit a book only swaps the person's life with it's contents. Kyle was relived it was a math book and not some porn, and was also relived to be in pants again so he laid low again.
By the end of class, he found himself talking to the shy asian girl named Kim that was in his class. Kyle noticed immediately his valley girl accent was replaced by a bookworms squealing. The two "girls" walked out of class as Kyle tried to figure out what to do in the life of a now nerdy Barb.
