Calvin has construction paper feather hanging off him. He tells Hobbes he's going to fly. Hobbes asks Calvin that if paper feathers were all that were needed, wouldn't they have heard about it before now. Calvin tells him it takes an uncommon mind to think of these things. Hobbes agrees with that. They come to a gorge. Hobbes asks if Calvin is going to jump off. Calvin tells him he'll need momentum, so he wants Hobbes to throw him off the edge. Hobbes tells Calvin he assumes no responsibility for this. Calvin isn't worried, he gets the patent. Hobbes heaves Calvin into the air. Calvin yells that he's flying. But down he falls into the gorge. Hobbes yells down for "Orville" not to sell the bike shop. Calvin tells him to shut up and to get him some antiseptic.
