Calvin and Hobbes hop out of bed. They read the paper, run outside to play, dig for dinosaurs, look under rocks for bugs, play Calvinball, fight, hit Susie with a water balloon, run from a snake, look at the moon, and catch fireflies. Mom drags Calvin inside to bed. Calvin says summer days are supposed to be longer, but they seem shorter to him. Hobbes says they didn't get to do half their itinerary.
