Bart has a bad luck during his test on the history of the USA. This makes him desperate, so he asks for help from the well-known genius Martin Prince. In return he promises to teach him how to be cool and forget about all the humiliation from the school popular guys. But Bart was too convincing or had put too many efforts and Martin just lost all his interest to school and to the study. Unfortunately that didn't help Bart to pass the test. In another episode Homer takes part in the experimental program which is developed to improve the hair growth. So after he has much more hair Marge finds him much more attractive and even sexy.
