Captain Underpants

The story begins with the school troublemakers, George Beard and Harold Hutchins, playing a series of practical jokes that cause their school to lose a football game. Their Principal, Mr. Krupp, gets so angry at them he imposes a set of rules and requires them to spend every spare minute of their day, beginning at 6:00 AM., catering to his every whim. If they don't comply, Mr. Krupp threatens to show a surveillance video of George and Harold setting up the pranks that ruined the game to the team.

To avoid Mr. Krupp's tasks, George buys a 3-D Hypno-Ring (which they receive after 4-6 weeks of back-breaking labor) from the Li'l Wiseguy Company in Walla-Walla, Washington, so they can get Mr. Krupp to hand over the incriminating video. Harold replaces it with one of his little sister Heidi's "Boomer the Purrple Dragon Singalong Videos". They then begin fooling around, telling Mr. Krupp he is a monkey or chicken. George hypnotizes Mr. Krupp to act as if he were The Amazing Captain Underpants, who is the hero of their homemade comic books. To their distress, Mr. Krupp, as Captain Underpants, takes the role seriously and departs to fight crime.

Captain Underpants confronts two bank robbers, and orders them to "Surrender! Or I will have to resort to 'Wedgie Power'!" The bank robbers fall down in hysterics and are apprehended by the police. The police begin to arrest Captain Underpants too, but George and Harold whisk him to safety on their skateboards.
