Calvin and Hobbes by Bill Watterson for March 15, 1990
Calvin: Mom! Hobbes is reading my comic books! Tell him to stop! I told him to go buy his own, and he snarled at me! Make him give 'em back! Mom: Maybe you should be glad he's more literate than most stuffed animals. Calvin: Buy they're my comic books, not his! Mom: Well, you should learn to share. I don't think Hobbes will hurt them. Calvin: Are you kidding?! he drew a mustache and glasses on every picture of nuke-man last issue! In pen! Mom: Why don't you go play outside, Calvin.
