Homer suddenly becomes smart thanks to an experiment! Much to the delight of his daughter Lisa, but the rest of the family is far less thrilled about the downsides of this IQ boost. Plus, Homer steps into the wrestling ring, Krusty the Clown establishes his own kingdom, Marge opens a chaotic daycare, and Bart competes in a death-defying snowboarding race! All these delightful stories and many more can be found in Simpsons Deluxe Volume 4!
