The first mentioning of Calvin's grandfather. (May 25, 1986)

Calvin's grandfather is mentioned during a scene on May 25, 1986, where Calvin smokes a cigarette and winds up in a coughing fit. Before he does this, when Calvin asks his mother if they have any cigarettes, she says: "Sure, Calvin. I think your grandfather left some in the back."


A reference was made to Calvin's maternal grandfather when Calvin is describing him to Hobbes, echoing Bill Watterson's complaint that comic strips are too small and now look like xeroxed talking heads (complete with the strip being done with Calvin and Hobbes as motionless "talking heads"). Hobbes then tells Calvin that his grandfather takes comic strips seriously; Calvin says as a result, his mother is looking into nursing homes for him, implying that this grandfather is maternal.
