Dan has been dating Kitty for a few months now, he can’t believe how hot she is, even if she is a complete bimbo. He keeps finding it odd how she is a member of the Cerebrum super pulchritudinem (note: Latin for brains over beauty) sorority, which is strangely made up a few brainless hotties like Kitty but mostly filled with mediocre looking brainy girls.
An old friend of Kitty’s eventually approaches him, Miranda shows him pictures of Kathrine as she calls Kitty before she became a member of the sorority, she was ok looking but from the pictures clearly very smart. Miranda says that the sorority has some sort of curse on it that got Katherine, every term one of the girls becomes a bimbo while the others get smarter. Miranda is trying to find a way to break the curse but she needs Dan’s help as Kitty is avoiding her.
Dan thinks things over, and decides to discuss Miranda’s theory with Kitty, after all he loves his hot bimbo girlfriend for who she is now, plus he noticed while Miranda looked happy in the pictures Katherine didn’t. Kitty when she hears of this pouts and drags him into the sorority house and has him tell the Sorority president. She thanks him for the information and asks Kitty to show him a good time in her room while they resolve this.
After a very good time with Kitty, the president calls him, he finds Miranda restrained in a chair and is a little worried. President admits that the sorority is indeed cursed, but it was one of their forbearers making, girls who pledge to this sorority are told of the curse outright, though those that fail to stay forget afterwards, so its stayed no more than a campus rumor. The curse is such that among each freshman group of sorority recruits one of them will become beautiful and brainless while the other girls gain more intelligence and lose a small amount of beauty. Therefore the women of the sorority have a chance to increase their intelligence the attribute most place the highest value on, while one among them gets to live the fantasy some have of being a popular school beauty.
Miranda argues that Katherine couldn’t be happy being the sacrifice, the president sighs and calls Kitty in, using some magic she temporarily restores Kitty’s intelligence, she admits she is happy, she no longer feels pressured by her intellect and she really does love Dan. Plus Miranda was never a good friend to her, she always teamed up with her for projects to leech off her hard work and she figures since she’s changed Miranda’s grades have tanked and she just wants her tutor and homework doer back. Miranda still doesn’t want to believe this so the President decides to admit her to the sorority, as she places the magic stamp on Miranda’s forehead she begins to transform. The President admits the curse is random when the stamp is applied to the pledges hands, but always results in bimbo transformations when applied to the forehead. Soon Miranda is a bubbly happy bimbo, her intelligence granted at Dan’s request primarily to Kitty to make her a little smarter, the rest going out among all of the rest of the sorority. Dan asks what will happen to him since he knows the secret. The President says they are very careful to make sure their more brainless sisters find good men, otherwise he would have been separated from Kitty long before this. He had proven himself when he told Kitty of Miranda’s plans, so long as he didn’t do anything to make Kitty unhappy he was fine, if not well the Cerebra Sorority was full of very creative minds to think up ways to get revenge and the stamp had a few more tricks she could display for him.
Dan steps back and says he understands, so what will they do with Miranda now? The President asks if he has any good friend needing a girlfriend, Dan smiles thinking of his best friend and roommate Miles a bit nerdy but always a good guy who has been jealous of his good fortune and asking him if Kitty had some friend he could introduce him to. The two are seen in the end years later having a double wedding Miles to Miranda now calling herself Meadow and Dan to Kitty.
