Calvin and Hobbes by Bill Watterson for December 05, 1986
Mom: Rosalyn, we're going to be a little later than we expected, so I thought I'd better call you. Rosalyn: That's fine. Calvin went to bed early, so I'm just holding down the fort. Calvin: Who's on the phone? Is it my mom? I want to talk to her! Mom! Mom! Can you hear me?! Come home now before it's too late! Help! Help! Rosalyn: No, that's just the TV. I'll see you at 11:30 then. Enjoy the play.
