Patrick Smartpants

One day, SpongeBob and Patrick are jellyfishing at Jellyfish Fields, looking for the many jellyfish to catch and having fun together. While playing tag, SpongeBob notices that Patrick is running towards a sign that says "DANGER CLIFF" and tries to warn him. However, Patrick does not pay attention to where he is going, and ends up running through the wooden sign and off of the cliff while still trying to read it. SpongeBob rushes down to the bottom of the cliff shortly after, hoping to find Patrick, but just discovers the top of his head. Patrick's body then walks up to him, much to SpongeBob's relief, and he screws the head back on. Suddenly, Patrick's brain starts working in ways it never had before; he seems to be interested in nature, art, science, and almost any music, losing interest in all the activities he and SpongeBob enjoyed. SpongeBob is initially confused and then left heartbroken when Patrick ends their friendship, declaring they have "grown apart." Patrick actually has fun with Squidward and Sandy, bonding with them over music and mathematics, respectively, but quickly drives them both away with his patronizing attitude; Patrick cannot stand Squidward's less-than-stellar clarinet playing, telling him to find himself a new mentor and ends up insulting Sandy by implying she can't solve more sophisticated "remedial equations," causing Sandy to order him to leave, but not before exclaiming that she likes him better as a "barnacle head." Since he is too smart even for them, Patrick begins to feel lonely over not having a friend to share his knowledge with. SpongeBob and Patrick sadly look over their scrapbooks together, leading Patrick to want to have fun with his best friend again. He tries many solutions to his problem, such as comparing his X-ray with SpongeBob's, meditating, doing research on Squidward, reading books about smarts, and even growing hair, but none of these things seem to work. Eventually, Patrick kidnaps SpongeBob and tries doing all of the things he used to do with him together, including jellyfishing and clam surfing, but cannot seem to regain his enjoyment. However, when SpongeBob mentions that Patrick stopped having fun after jumping from the cliff and knocking off his head, Patrick gets an idea. He redoes his actions by running through the wooden sign and falling off the edge again. When SpongeBob finds him at the bottom of the cliff, he is still smart. Patrick asks SpongeBob to confirm where his dislodged forehead was found the first time and uses his intellect to deduce where it actually landed when he fell. They discover that SpongeBob had in fact found brain coral rather than Patrick's forehead, explaining how he became so smart when it was attached to his head. SpongeBob asks if Patrick really wants his original forehead back, to which Patrick declares his newfound knowledge is not more important than friendship. SpongeBob puts Patrick's original head back, which renders him back to normal. SpongeBob and Patrick make loud, obnoxious noises and start giggling before running off together, ending the episode with the former happy to have his best friend back.
