Calvin asks Hobbes for some help with his homework. He's supposed to write a paper with two points of view, then defend one of them. He can't think of anything to argue. Hobbes says that's hard to believe. Calvin says he's always right, and everybody else is wrong. He wonders what there is to argue about.

Calvin wants help with thinking of an issue for a debate paper. Calvin doesn't care about issues. He says he's got better things to do than argue with every wrong-headed crackpot with an ignorant opinion. He says he's a busy man. Calvin says either agree with him or take a hike. He's right, period. Hobbes rolls his eyes and says Calvin's right. Calvin says everybody's happy.

Hobbes suggests they put on thinking caps to come up with a writing topic. As they run to get thinking caps, Calvin asks where he would be without Hobbes' suggestion. Hobbes replies that conceivably, he might be working on his assignment.

Calvin uses a colander as a thinking cap. Its metal surface will conduct brain waves. Hobbes attaches input and output strings, and a grounding string. Hobbes asks why a grounding string. Calvin replies he wants to keep his ideas grounded in reality. Hobbes thinks he's too late. Calvin says they also must build a transformer for the atomic cerebral enhance-o-tron.

Calvin's thinking cap is ready. Hobbes turns it on. He asks if it worked. Calvin takes off the thinking cap, and his head is bigger.

Calvin says a consequence of his cerebral augmentation is that his brain swelled. Hobbes asks if he can have Calvin's hats. Calvin says his brain is unraveling all the mysteries of the universe. He says natural laws can be reduced to one simple, unifying equation. Hobbes asks what that is. Calvin says his powerful brain is bored with such simple problems. He's now working on why girls are so obnoxious.

Since Calvin's brain has enlarged, Hobbes thinks he can write his paper now. Mom calls Calvin for dinner. Hobbes wonders what will happen when Calvin's parents see his head. Calvin's powerful brain finds an answer. He'll wrap his head in a bedsheet. Hobbes thinks Calvin's powerful brain knows something he doesn't.

Mom calls Calvin to dinner again. Calvin has a turban on his head made from his sheet. He tells Dad he was unavoidably detained. Dad tells him to take the sheet off at the table. Calvin does, and Dad thanks him. Calvin, with his larger head, says they never notice anything.

Calvin brings some fish to Hobbes. Calvin doesn't need brain food with his enlarged brain. He applies his brain to the homework problem. Hobbes asks how it's going. Calvin says he just remembered what the assignment was.

Calvin comes up with a topic for his paper. He'll debate whether tyrannosaurs were predators or scavengers. Hobbes asks which side he'll defend. Calvin tells Hobbes he believes they were predators. They're so much cooler that way.

Calvin says he'll start with carnosaur evolution. He'll delve into skeletal structure, skull design, and environmental factors. First, he'll draw pictures of a T-rex eating people at the museum. Hobbes notices Calvin's head shrinking back to its normal size.

Hobbes says Calvin's head is back to normal, but Calvin hasn't written his paper yet. Calvin says the hard part was getting a topic. He says he'll write everything he knows about tyrannosaurs. It's a breeze. He says he's guaranteed a good grade. Mom tells him it's time for bed.

A robot doctor looks at Calvin. It slices his head open to look at the brain. The doctor puts more brains into Calvin's skull. The robot doctor asks how Calvin feels. Calvin says "smart". The doctor says the knowledge implant should provide all the wisdom you'll need. Calvin walks out of the office needing no more school. The robot doctor says to go home and have 12 years of fun. Calvin sighs as he gets onto the school bus.

Calvin tells Mom he hasn't finished his school paper yet. She asks how much more he has to do. Calvin tells her he just has to write it.

Mom asks what Calvin has been doing all night. Calvin tells Mom he built a thinking cap that augmented his brain to think of a topic. Mom says that doesn't sound like a good time budget to her. Calvin wasn't expecting to get audited so soon.

Calvin gripes to Hobbes that Mom is only giving him an extra half hour to write the paper. He asks how he's supposed to do a good job in such little time. Hobbes reminds him that Mom said he wasted the whole evening. Calvin complains Mom is making him to a rushed, sloppy job. He won't get the "A" he deserves. Hobbes tells him he's used up 15 minutes complaining about it.

Calvin crawls into bed. Hobbes tells him at least he's finished with the paper. Calvin says it could have been better. He gets a chance to write about something he knows, and he has to rush the whole thing. Hobbes says he did the best he could with the time he had.....sort of. Calvin thinks geniuses should be given special considerations.

Calvin reads his paper in front of the class. He reads that tyrannosaurs were predators, because it would be bogus if they ate things that were already dead. He grins at the class. He yells that he's a concise writer.

Calvin tells Hobbes he got a "D-" on his paper. He talked to Miss Wormwood about having run out of time. He tells Hobbes that Miss Wormwood admitted that maybe he'd picked too complex a subject. She raised his grade to a "D" and said to pick realistic goals and plan his time better. Hobbes asks if he learned a lesson. Calvin says he did. Smooth-talking the teacher really pays off.
