Synopsis:
The parents of Smallville students are invited to teach classes for a day at Smallville High School. Jonathan Kent is appointed parent principal. Soon, Jonathan begins acting like a tyrant, instituting senseless rules. Clark tries to discover the reason for his father's strange behavior. After following several false leads, he finally determines that Pa Kent ate a rare herb that causes "Jekyll and Hyde" behavior. Professor Lang gives Jonathan the antidote, and Pa Kent returns to normal.
