It's possible that you might be thinking of a specific literary genre or trope that uses the idea of foolishness or silliness. Some examples could be:
* Folklore: Many cultures have tales featuring characters known for their foolishness, often leading to comical situations or moral lessons.
* Comedy: Comedies often feature characters with comedic flaws or who make silly mistakes.
* Satire: Satire can use exaggerated characters and situations to criticize society or individuals.
If you have a specific story or piece of literature in mind, it might be helpful to provide more context about the characters or themes. This would help me understand what you're looking for and whether there is a specific literary term that fits the description.
