Calvin and Hobbes by Bill Watterson for November 21, 1995
Mom (Calvin's mother): Hello? Calvin: Hi Mom, it's Calvin. Mom (Calvin's mother): Is something wrong? You're supposed to be in school! Calvin: It's recess. I'm fine. Mom (Calvin's mother): Then why are you calling me? Calvin: Actually, I'm calling Hobbes. Would you put him on? I gotta get my own secretary.
