Calvin and Hobbes by Bill Watterson for July 10, 1992
Calvin: Here I am. All set to write my autobiography. And I'm stuck! Hobbes: What's the problem? Calvin: I can't remember the whole first half of my life! Hobbes: Maybe your mom knows what you did. Calvin: I asked her. She said I did revolting things that are probably unpublishable. Hobbes: Well no wonder you suppressed the memories. Calvin: Maybe I was in jail!
