Calvin is reading his homework. He says it's boring. He asks how he's ever going to read three whole pages by tomorrow. It's impossible. He hits his book and says nothing's impossible...for Stupendous Man. He runs out of the room.

It's Stupendous Man, lover of liberty. He notices Calvin (his 6-yr-old alter ego) has three pages of boring homework to read. It's tyranny! Stupendous Man could easily read the assignment with his high-speed vision, he has a bolder plan. The caped combatant concludes there's no need for homework if there is no school tomorrow.

Stupendous Man flies to the observatory telescope at Mount Palomar. With his stupendous strength, he carefully unscrews the giant lens and blasts into space with it.

Stupendous Man circles the earth with a 200 inch telescope lens. Aligning perfectly to the sun, the magnifying lens focuses the terrible solar energy....and fries a certain elementary school clean off the map. Stupendous Man flies into the bedroom window saying Calvin has no need of ever doing homework again. Liberty prevails!

Mom calls into the bedroom asking if Calvin is doing his homework. Stupendous Man recognizes his arch-nemesis, Mom-lady. He doesn't want her to discover his secret identity. He goes into the closet to change back into his alter ego, Calvin. Mom enters the bedroom looking for Calvin. Calvin, in the closet, notices that Stupendous Man's cape has gotten caught in Calvin's zipper. Mom opens the closet to see Calvin standing in his underwear. She says she can tell this is going to be a good one.

Mom asks why he's standing in his closet in his underwear. Calvin says because it was hot. Mom reminds him he's supposed to be doing his homework. Calvin tells her he doesn't have to do it, thanks to Stupendous Man. He explains how Stupendous Man fried the school with a big magnifying glass in space. He's sure it will be in all the papers tomorrow. Calvin, sitting at his desk reading his homework, grumbles that she'll be in trouble when she gives him his costume back.
