Calvin asks Mom if they have a shoe box for a school project. Mom gets him one. Calvin is going to make a diorama. They're studying different ecosystems, and Calvin's making a desert scene. Calvin adds that he'll some glue and paper. He's going to build a cactus and a roadrunner. Mom asks when it's due. Calvin tells her today, but Calvin told the teacher he wasn't quite finished.

Calvin complains to Hobbes that Mom had a conniption when she found out he hadn't started his diorama that was due today. Calvin asks what the big deal is being one day late. Lives don't hang in the balance. The fate of the universe doesn't depend on his handing his desert scene on time. Hobbes thinks that's keeping things in perspective. Calvin adds that even if lives were in the balance, it would depend on whose they were.

Calvin figures he can't build a desert diorama if he doesn't know what a desert looks like. He complains that Mom and Dad have never taken him to a desert for him to know this stuff. Hobbes asks why he doesn't get out a book. Calvin asks if he should go through all that trouble. He says he's a busy guy. He's got other things to do with his life besides this. Hobbes says why waste time learning, when ignorance is instantaneous. Calvin says his TV show starts in 20 minutes. He asks if Hobbes is going to help him or not.

Calvin asks Mom for some papier-mache. Mom says they don't have any. Calvin wonders how he's supposed to make a roadrunner without papier-mache. Mom says he should have thought of that before 7:00 at night. Calvin asks how he'll make one. Mom tells him it's his project, he should do the work. Calvin tells her that if he gets a bad grade, it will be her fault for not doing the work for him.

Calvin tells Hobbes he's almost finished with the diorama. Hobbes says that didn't take too long. Calvin replies that's because he's a genius. Hobbes doesn't see the roadrunner. He asks if Calvin wasn't going to put one in. Calvin points out the cotton balls he glued down. He says the roadrunner just ran out of the scene, leaving those clouds of dust.
