Plot
Patrick walks into the Krusty Krab and notices a new item on the menu. It is called a Smarty Patty. SpongeBob tells Patrick that if you eat the patty, you become very intelligent! Patrick orders the patty and eats it, suddenly feeling a tingle in his brain. Patrick then runs out of the Krusty Krab and announces to the whole world he has now become intelligent. Squidward then tells Patrick that the patties don't make you smart, it's just a promotion. Patrick and SpongeBob ignore him and run off to a nearby college. Squidward and Mr. Krabs then team up to break the spirit out of Patrick so he can understand that there is no intelligence in a Smarty Patty. Meanwhile, Patrick solves a really difficult math problem correctly, and he is awarded heavily because of his intelligence. Patrick then opens up a new building for the college and teaches the students everything he knows. Mr. Krabs and Squidward suddenly break in and tell Patrick that a Smarty Patty is just a promotion, but the two are kicked out of the building. Mr. Krabs and Squidward walk out of the college defeated when they see a hillbilly eat a Smarty Patty and become super intelligent, while Sandy eats a Smarty Patty and becomes very stupid. Mr. Krabs then realizes that the ads were true, and confesses to Patrick he is a genius. Suddenly, Patrick then becomes stupid again, and walks out of the college with SpongeBob. The Smarty Patties continue to be sold, and this time, are with a warning for smart people. Plankton steals a patty and ignores the warning though. This time karma hit Plankton instead of Squidward.
