Calvin asks Susie if she wrote her report. She did, it took all the evening. Calvin says it only took him 15 minutes. It doesn't take long when you know as much as he does. Susie asks to see the report. Calvin tells her she won't be setting the grade curve this time. She reads the title "Bats: The Big Bug Scourge of the Skies". Calvin points out the professional, clear plastic binder. Susie yells that bats aren't bugs.
