Calvin and Hobbes by Bill Watterson for September 13, 1990
Mom: I'm home. Dad: How was your meeting with Calvin's teacher? Mom: Well, when we got to the classroom, we saw that all the kids had drawn self-portraits in art class, and had left the pictures on their desks so the parents would recognize their child's seat. Dad: That's a cute idea. Did you find Calvin's picture? Mom: There was one drawing of a green kid with fangs, six eyes, and his finger up his nose. Dad: Uh oh. Mom: The meeting went downhill from there.
