Calvin is standing there holding a balloon on a string. He starts floating up into the air. Higher and higher he goes as he clutches the string with both hands. As he floats along in the sky, he says this probably just goes to show you something, but he sure doesn't know what.

Calvin is really moving with his balloon. He sees the river and the town triangle below. Calvin yells down for someone to tell his tiger that he's blowing away on a balloon. He yells to see if anyone can hear him. He adds to tell Hobbes that he can't read Calvin's comic books, just because he isn't there. Finally, he adds to tell his parents what happened.

Calvin is heading for a flock of ducks. Calvin flies through their formation. He apologizes as he passes through. After he gets through, he looks back and says "If looks could kill".

Calvin's hands are getting tired. He decides to tie the balloon string onto his belt loop. After he does that, he flips upside down. The balloon pulls his pants down a little, his shirt falls over his head, and his underwear is showing as he hangs. He says that if a plane comes along now, he's going to die.

Calvin, now rightside up, supposes it doesn't get any worse than hanging from a helium balloon a mile over some unrecognized state. He thinks about it, and decides he could get sucked into a jet intake or his grip could weaken. As a bird comes near, he says that's one of the remarkable things about life. It's never so bad that it can't get worse.

Calvin is just going higher and higher. He supposes eventually the pressure in the balloon will be greater than the air pressure around it, and the balloon will....POP! A horrified look comes upon Calvin's face, and down he falls.

As Calvin plummets back to the ground, he says this must be a dream. He says when you fall from two miles up in the sky, you look down and gasp. Then you wake up. Calvin looks down and gasps. He keeps gasping as he keeps falling to the ground.

Calvin wonders if his life will flash in front of his eyes. He keeps tumbling down. He says that's the problem with being six years old, his life won't take very long to watch. He hopes he can get a few slow-motion replays of the time he smacked Susie upside the head with a slushball.

Calvin continues to fall. He thinks about having gum in his pocket, then blowing a big bubble. No gum in that pocket. He tries the other. He finds his transmogrifier gun. Calvin says those things come in handy all the time.

As Calvin gets closer to the ground, he has nothing to worry about. He had forgotten his transmogrifier gun. He just points it at himself, and he's safe. ZAP! Calvin turns into a floor safe and continues plummeting to the ground.

Mom and Dad are at the dinner table. Mom asks Calvin where he's been. Calvin explains that drifted away on his balloon which popped. Then, he remembered his transmogrifier gun. After mistakenly turning himself into a safe, he transmogrified into a light particle and zipped back home instantaneously. Calvin sits at the table. He looks at his meal. He then says that if he had known they were having that for dinner, he wouldn't have hurried. Mom tells him to sometime try transmogrifying into someone who occasionally makes an ounce of sense.
