Step by Step S02E22 - The Psychic

As a practical joke, J.T. places an unflattering baby photograph of Karen in the high school yearbook. Later - after Cody and J.T. visit a psychic - J.T. becomes convinced that a dark-hair female will stab him to death with a large knife, and that profile fits Karen. Also, Frank and Carol purchase a new massaging bed, but the bed does everything but help them relax or enjoy a good night's sleep.
