Calvin and Hobbes by Bill Watterson for July 21, 1990
Transcript:
Calvin: I did it, Hobbes! I did just what you said! I put a stick in the spokes of my killer bicycle! When it tried to chase me, it flipped over! I wrestled it to exhaustion, and then I let the air out of its tires! Ha! I guess that nasty ol' thing won't be coming after me any more! We're too smart for it! Man triumphs over machine! Mom: Training wheels! What a good idea! Dad: I pumped up his tires too. They were both flat.
Killer bike: Nice going, old man. Here comes double the tracks on Calvin’s face.
