Calvin and Hobbes by Bill Watterson for December 01, 1989
Calvin: Oh brother! Another "Discussion" about my study habits and the importance of homework. I tried explaining that it's hard to study when one's size suddenly starts increasing, but does she care?! Hah! No, it's just blah blah blah like it's all my fault! Mom's never been as big as a galaxy, so she can't understand how anyone else could be! Sheesh. Oops, it looks like she's wrapping up. Better start nodding. Mom: Good, I'm glad we had this little talk.
