Calvin is a young boy who is a genius and attends the Enriched Learning Center for Gifted Children.


According to Ms. Melon, he and Tanya had argued that free will is an illusion. Later at lunch, he and his apparent best friend Sydney Swift were making fun of Bart Simpson's stupidity. He asked Bart to swap the weight of a bowling ball on the eighth moon of Jupiter to the weight of a feather on the second moon of Neptune for his lunch. Bart said yes, so Calvin gave him a small grape and took his huge sandwich. Later, he was talking to Sydney and Ian, where he stated Bart is "just not very bright at all".
