Calvin and Hobbes by Bill Watterson for October 22, 1988
Calvin: I hate school. Calvin: Each day I count the hours until school's over. Then I count the days until the weekend. Then I count the weeks until the month is over, and then the months until summer. I always have to postpone what I want to do for what I have to do! Dad: Welcome to the world. Calvin: Would you sign this parental excuse to get me out of the next 11 1/2 year of school.
