With graduation and a dissertation on the way, Carson is rapidly following in his father's footsteps—except for when Dad turned himself into a bimbo, abandoned his family, and ran away to live with a rich man. He had been so smart before. A renowned biologist. And then he willingly erased his intelligence in favor of being dumb and giggly. Carson is still trying to understand why his only role model decided to be so stupid. And he believes it's worth trying to get his real father back.
In his father's study, Carson finds the pink serum responsible. He has a sip in order to better understand Dad's decision. However, Carson's first and repeated temporary sprees as a ditzy bimbo don't help him find a cure; they begin to convince him that Dad maybe had a point about being dumb and girly.
