The Calvin and Hobbes Wiki

Calvin at his desk

Calvin's Desk at school is a recurring element that is usually featured when Calvin isn't paying attention in class. It was first seen on November 21, 1985, when Calvin brings Hobbes to class to help him on a test (but the plan evidently doesn't work, as seen when Hobbes says that 7+3 is 73).
