Calvin and Hobbes by Bill Watterson for April 05, 1989
Calvin: Wow, Susie got sent to the principal's office! She's in trouble right now, all right! *Wheww* I sure was lucky the teacher blamed Susie for everything. What a break! Oh, no! What if Susie rats on me!? Suppose they make her sing! Suppose she squeals! Suppose she fingers me! Susie: Oh, I'm so relieved. I was afraid you wouldn't believe me. Principal: Oh, yes, we've got quite a file on our friend Calvin.
