Calvin and Hobbes by Bill Watterson for January 28, 1988
Susie: What are you doing?! You're doodling! You're sitting here drawing martians when we're supposed to be researching! You haven't done anything yet! Don't you care?? What's the matter with you?! It's no use! We're going to flunk! I'll have to go to a second-rate college because my idiot partner spent the study period drawing martians! Why me? Why me? Why me? Calvin: Here. This will cheer you up. The martian moves when you flip the pages! Watch, you can see him eat an astromaut!
