Calvin and Hobbes by Bill Watterson for November 21, 1989
Transcript:
Calvin: I'm telling you, my personal gravity recersed its polarity! I fall up now! I've been trapped on the ceiling! I couldn't do homework up there! My desk is on the floor! You should be glad I wasn't outside when it happened, or I'd be sailing throught the ionosphere! Mom: Right. Now I don't want to hear any more nonsense until you're through with your homework, understand? Calvin: Don't let go! Don't let go!
