Description
A college professor is certain that life exists upon other worlds, but can't quite remember why he is so assured of this fact. One evening he is abducted by aliens and he receives his answer. The aliens tell him the reason for his abduction is that years ago the aliens sent a spy to Earth, but failed to hear back from him, and the captain of the spaceship realizes that he should not have sent an absent-minded spy. The professor realizes that he is the alien spy.
