A Crossed Reality

Randy, a Harvard student who was ahead of his time in the field of science, set out to prove to his professor that alternate realities were more than science fiction nonsense, and while doing so, he had inadvertently caused himself and six of his friends to switch bodies with their alternate selves of another reality. To make matters worse for Randy's six friends, Randy, the only one of the seven who could correct the crossed reality, wasn't attending Harvard nor was he in his hometown.
