However, you might be thinking of a few situations:
* Rock Lee's training: Rock Lee is known for his intense training, which often involves him wearing very little clothing, including only a tight-fitting training outfit. This might lead to some comedic situations involving the tightness of his clothing, but not necessarily his pants falling down.
* Accidental falls: There are many action-packed scenes in Naruto where characters might trip or stumble, potentially causing a wardrobe malfunction. However, these are usually depicted as minor slips and not as a focus of the scene.
* Fan-created content: There are many fan-made comics, illustrations, and animations of the Naruto characters that might depict comedic situations, including pants falling down. These aren't part of the official canon.
It's important to remember that Naruto is a shonen anime with a focus on action, adventure, and ninjas. While humor is present, it is usually integrated into the plot and character development rather than relying on slapstick or physical comedy.
