My favorite type of stupid-kid stories are the ones where they try to get away with things but are impeded by their obviously low ability to reason and avoid making a complete ass of themselves. It's that kind of behavior that gives us hope that should they become criminals some day, they will be easily apprehended and the world will be a safer place.
Student skips (or "ditches" as we used to call it in MY day) a class and stupidly walks past the class in question in full view of the teacher.
Student skips a class then makes it onto the school's daily TV announcements filmed in the school hallways during the time he's supposed to be in class. Added bonus that he was grinning and waving into the camera like a complete idiot.
Student can't formulate a sentence using words that have more than one syllable, and yet produces homework with sentences such as this: "Intrepid Polynesian sailors in outrigger canoes were the first humans to reach the Hawaiian Islands". Riiiiiight.
