Calvin and Hobbes by Bill Watterson for August 17, 1990
Mom: Calvin, I asked you to clean up your room. Calvin: I did! Mom: Well, you didn't do a very good job then. It looks as messy as it did before. You should take pride in what you do, and always do the best job possible. Calvin: I don't need to do a better job. I need better p.r. on the job I do.
